Fixes #7900, add test for this problem (Common not being available at the start of the script) in ArchiveCronTest.php by executing the real archive.php w/ the --help option.

In ArchiveCronTest make sure to use real translations, because for some reason cron archiver will fail when archiving segments if translations aren't available. Segment archiving requests return the token General_DateRangeFromTo w/o anything else (only some of them).

Fixing ArchiveWebTest, now that test.php is used (which disables the logger), we must enable it in a test class override method, since this test checks the log output.

Fixing LogTest now that NullLogger is used for test environment setup.

Make sure translations are loaded in EnvironmentValidationTest.php.

Make sure the logger is enabled for ArchiveCronTest.

Refactor CronArchive, remove need to specify URL (also did same to CliMulti), remove test skipping in ArchiveWebTest & ArchiveCronTest.

refs #6753 uncommenting tests to see whether they fail. Cannot execute them directly as I am using PHP 5.3

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

Remove unnecessary archive table deletion in archiver tests (tables deleted by database drop in fixture setup).

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

Refs #4827 Adding test case: segment is pre-processed, and test both cases: with, or without URL encoding

Trying to re-enable these tests now that we've rewritten how archive.php works, maybe this will work better?

- Rename *_BaseFixture to Fixture.
- Move DB setup code to Fixture and reuse code in DatabaseTestCase.
- Make IntegrationTestCase::$defaultApiNotToCall an instance var.
