fix tests as reports are invalidated now in some tests causing the site creation date to change causing archiving more dates

refs #5940 moved files into a subfolder framework, added autoloader to remove duplicated code to load autoload.php and to be able to register more autoloaders (eg for test files) on demand. This I got read of many includes that had to be updated all the time and that had to be updated all the time when moving iles

refs #5940 we might stay backwards compatible this way for 2 months. moved some tests from unit to integration and explained when a test is a unit test, an integration test or a system test.

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

fixes #5933  New $period parameter to the API call CoreAdminHome.invalidateArchivedReports refs #6116

  - moved all API URL generation logic & API response handling logic to separate classes
  - created ApiTestConfig class to hold API test options (and documentation for properties)
  - remove unnecessary IntegrationTestCase properties and methods (including apiNotToCall/apiToCall)
  - remove as many unnecessary API test options as possible (including abandonedCarts, hackDeleteRangeArchivesBefore)
  - rename checkRequestResponse to assertApiResponseHasNoError

Refs #5800, add namespaces to integration tests in root folder. Also add IntegrationTestCase to a namespace, re-add individual test @groups, move test groups to class level, and rename test files & class names so underscores are not used.

Piwik is a free/libre analytics platform. Refs #4455 GNU Package requirement to use free/libre instead of open source

Fix bug (missing getInstance()). Exception was not shown because tests were not rethrowing the exception

Removed many Piwik_ functions, in Piwik 2 it is best practise to use the methods calls instead

Todo: finish converting core/ classes + convert plugins/ classes to use \Piwik\Plugin namespace + fix build + Merge master

Converting Piwik core source files, PHP, JS, TPL, CSS

Refs #2908, refactored tests so database setup (adding sites, tracking visits) are separated from API tests. Put setup code into fixtures and reused code as much as possible.

while setup (atm bulk tracking doesn't work)

refs #3227 refactored integration tests to setup database and tracking only once per class; that should speed up the tests a bit
