Remove dates from the XML being compared since the test tests with last7, {day-6},now and {day-6},today which read differently but refer to the same date

refs #3158
 * adding more report exceptions from being filtered by AddColumnProcessedMetrics filter 
 * I forgot to manage an edge case when $label=false and there are no data, what should the API return ? see @review
 * only retrieve the last period when looking for top n labels

 * API functions returning data now have a new optional 'segment' parameter. segment can define a Visitor segment dynamically that will be applied to the report. For example, &segment=country==FR;actions>=3 (AND, OR supported. Only == and != supported currently, but easy to add more)
 * For API requests with a segment parameter, the reports will now be processed on the fly, and only the requested plugin report will be archived.
 * All plugins now define the 'segments', with a name, category, SQL field, filter, etc.
 * Simplifying archiving code a bit
 * Fixes #2069 Exit rate computation
 * New widget: lists the Top Keywords for a page URL, Widgets for a website only. Maybe later we could create a widget category "For your site"?
  * This widget is pretty cool SEO wise, but maybe the PHP snippet should do caching (not so good hitting the API on each page view... but why not?)
 * still to do!

Also adding integration test suite in place.

 * Adding new mechanism to trigger known tracking requests, then call all API methods get* and compare XML to the previous 'expected' XML.
 * make sure overwritten config files are not read during tests. Use defaults from global.ini.php.
 * piwik.php Tracker allow calling script to force Datetime and user IP for a specific request. 
 * Wrote 3 main tests
  * wrong tracking requests should not return error and should not record anything 
  * standard one visitor, 2 visits, with page view, download, outlink and goal tracked
  * Added integration test as an example in the ExampleAPI plugin (pretty simple to add testing code)
TODO 
 * Finish PiwikTracker and show it in UI
 * Show how to use image based tracker in UI
 * Add more tests (multi periods and multi sites) in Main.test.php
 * Fix failing Config.test.php test (when ran via all_tests.php doesn't fail otherwise)
