Fixing BlobReportLimitingTest. Fixture::createConfig has no effect now, and setting config must be done after environment is created.

Remove GlobalSettingsProvider interface and replace w/ GlobalSettingsProvider class, the class is the old IniSettingsProvider class.

Remove uses of Config::init(), Config::clear() and Config::setTestEnvironment(). Replace last w/ mock config class, which is closer to use of DI.

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 #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
