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

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

- Rename *_BaseFixture to Fixture.

refs #4233 moving tests that require a database to integration as those are integration tests per se

refs #3089

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

Converting Access & Auth to namespace
