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

Refs #3632 Creating a test case: same visitor (same IP + idvisitor) visits the website on two different days.
Visitors on second day is marked as "new" because window_look_back_for_visitor is not set.

Forcing all recorders and recorders max payload to 1, to prevent random behavior (eg. in Live.getLastVisitsDetails, the pageIdAction may be random order if recorders import data in random thread order)

 * Now possible to track up to 5 Custom variables per Visit. Also, Goal conversions will be reported 'By custom variable name & value' 
 * New report in Visitors > Custom Variables, new CustomVars API
 * Updated schema
 * Updated PiwikTracker PHP api to allow setting the name,value pairs

Code style
 * Refatoring some API code, and Archiving queries 
 * Changing text from 'segment' to 'dimension' as this is better description + we want to build actual segmentation later
 * removing getJs calls in some plugins since they only included sparkline.js, moved to CoreHome

Fixing bug in Archiving found with this new test suite (max_actions was incorrectly summed during archiving, rather than max() operation)
Updating expected file as naming convention changed in previous commit
Refs #1446

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)
