Fixed getCurrentUrl() and getCurrentUrlWithoutQueryString() + tests

Note that I still do not understand how this could be triggered, hopefully if we log we will gather more info about issue.

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

we will deprecate old test classes in 4 months and not in 2, simplified test run by only allowing short version, added some examples

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
