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

and restore Transitions tests which I deleted by mistake earlier

Make sure provider segment suggestion values use non-prettified provider values, add tests for getProvider report & provider segment, and fix build.

 * Implementing Custom Date range in Core, eg "period=range&date=2010-01-05,2010-02-03"
 * Only the requested plugin's report will be processed, ensuring fast responses
 * when a large period is requested, the code will try and select an optimal number of sub periods (see Range.test.php) - a mix of weeks, months and days inside the requested range
 * adding integration testing + unit test for optimal subperiods algorithm

TODO
 * we should also use Yearly archives whenever possible (when date range is very large)
 * if custom date range start date == website creation date or before, can use more optimal subperiods (using starting month / year / week)
 * Test/implement "last N days" 
 * Test with timezones when the custom date range ends today
 * UI to allow selecting custom range (show 2 calendars)
 * Update API reference doc + add example in API page listing
 * Add "last 7 days", "last 30 days" in the user settings for "Default date to load"
 
NB: 3 tests fail in Main.test.php on my box, but I'm really not sure why... let's see if Jenkins fails as well
