* referrer tests

* Core system tests

* Log Analytics is compatible with Python 2.7

* Note

* Submodule

* UI tests: Gender neutral

* No longer any segmentValue in subtables, this was a bug
* Referer.getReferrerType should not have any segments
* Order of some segments slightly changed in metadata output since we
  do process them earlier now
* Append segemnt refererType=search to keywords

refs #5940 put tests in correct folders, better testsuite names, some tests still fail and I cannot figure out why

Refs #2781 PR #121 Modifying tests fixtures to generate visits from two countries so that it's clear that the Segmenting on the country selects only that country.

 * updating all variables/methods containing Referers
 * RENAMING custom segments definition, and custom scheduled reports definition, so that when they load "Referers" segment/report it still works as expected
 * RENAMING old archived data so that archived blobs are called Referrers
  * Reverting part of 0deb2bbb
  * Update integration tests generating PDF+HTML with images on my dev box (GD 2.1 and PHP 5.5)

 * Metadata output now contains "imageGraphUrl"
 * the function used by piwik mobile and others, API.getReportMetadata now accepts period and date parameters
  * for "Evolution graphs" (goals, visitssummary, etc.) we must "plot" multiple days previous to the currently selected date. 
  The metadata APi automatically does the $date parameter rewrite, when period != range, and date is not already a range.
  Therefore the imageGraphUrl can be used as is.
 * New page available at: index.php?module=ImageGraph&action=index&idSite=1&period=month&date=2011-04-17
  * This page will call metadata APi then display the graph for all existing reports. This is a useful debug/test page to view all graphs as they will be displayed in Piwik Mobile (and PDF reports later refs #2706

Refs #1721
 * Showing less vertical bars in graph by default 
 * Displaying empty graph when there is no data

 * Adding price tracking on Ecommerce pages, via JS or PHP api. 
 * Displaying price in API field avg_price ONLY IF the product was NOT purchased. If a product was purchased, the "display price" tracked is not displayed and purchased price is used instead.
 * Price tracked with this feature will ONLY be displayed as "Avg_price" in Product Names, and Product SKUs ONLY WHEN the products havent been bought.
 * Hacking around tracking price for ecommerce items, using a custom variable and small custom hacks to the SQL to get the average price for each custom var.
 Similar to doing basic version of custom variables co variation
 * Allow custom variables values to be integer (previously would fail to record the custom variable)

 * Adding Product page/Category page view tracking via Tracking function: setEcommerceView: function(sku, name, category)
This is using the Custom Variables per page, using slot 3/4/5 to track sku/name/category
 * UPdated PHP tracker + JS tracker + adding tests
 * Items reports (best SKU/Name/Category) will automatically call the Custom Vars API and enrich the items reports with "Visits", "Conversion rate"
 * Updating integration tests + fixing bug when item is deleted from Cart, then added again (or purchased)

Fixes #2434 Now Actions.get* and Goals.get* (which were the two API not supporting all segments) have full support of all segments + adding tests

Refs #2432 
 * Processing Custom vars per page: they are merged in the existing Custom Variables output (rather than create a separate one)
 * So there is no need for a new Report in the UI, Custom variables of scope "page" are displayed in the "Visitors > Custom Variables" report
 * Displaying Custom vars per page in the Live API output

 * Now tracking Ecommerce Items (sku,name,category,qty,price)
 * zero, 1 or many items can be in a Ecommerce Cart (total), or an Ecommerce order (orderid, grandtotal, subtotal, tax, shipping, discount)
 * A Cart left at the end of a visit becomes an Abandoned cart. New reports separate orders from abandoned carts.
 * JS API and PHP API have 3 new functions (add items, track cart update, track ecommerce order)
 * JS stores timestamp last ecommerce transaction in id cookie so we can count repeat buyers
 * Goals.get API now returns stats for the two goals: ecommerceOrder and ecommerceAbandonedCart
 * new API functions to request Items (product) reports: getItemsSku, getItemsName, getItemsCategory. See doc:

  If you are tracking Ecommerce orders and products on your site, the functions "getItemsSku", "getItemsName" and "getItemsCategory"
  will return the list of products purchased on your site, either grouped by Product SKU, Product Name or Product Category. For each name, SKU or category, the following
  metrics are returned: Total revenue, quantity, average price, average quantity, number of orders with this product.
  
  By default, these functions returns the 'Products purchased'. These functions also accept an optional parameter &abandonedCarts=1.
  If the parameter is set, it will instead return the metrics for products that were left in an abandoned cart therefore not purchased. 
  
  The API also lets you request overall Goal metrics via the method "get": Conversions, Visits with at least one conversion, Conversion rate and Revenue.
  If you wish to request specific metrics about Ecommerce goals, you can set the parameter &idGoal=ecommerceAbandonedCart to get metrics about abandoned carts (including Lost revenue, and number of items left in the cart) 
  or &idGoal=ecommerceOrder to get metrics about Ecommerce orders (number of orders, visits with an order, subtotal, tax, shipping, discount, revenue, items ordered)
 * showing ecommerce orders/abandoned carts in the Live! API output
 * new segments: visitEcommerceStatus and daysSinceLastEcommerceOrder
 * these new attributes also appears in Live! API output
 * Fixes #1975 as side effect of cleaning up all this code this bug should now be fixed (bug was to use nb of conversions as dividend, rather than number of converted visits)
 * adding full integration test testing all possible use cases regarding Ecommerce carts/orders/items etc.
 * also integration testing the changes to piwik.js

 * Do not display Conversion rate from "All columns" view, when there is "per goal" metric available
 * Do not display conversion rate on the "Goals" view
 * Remove nb_visits_converted from the API when there is "per goal" metric
 * Revenue per visit, is now based on the sum of revenue for all goals, rather than trusting the "revenue" field in the visit (in case Goal Revenue was attributed to a Referrer that is different from the visit Referrer where this conversion occurred)

API Breaking: nb_visits_converted not already in response anymore (only when there is no "per goal" metrics for this report)
