Url: introduce global helper functions for cleanup and scheme detection

Relates to #314 & #326

Additions:
 - add global `cleanup_url()` and `get_url_scheme()` functions

Modifications:
 - replace `Url` usage in `index.php` by calls to global functions
 - fix `Url` tests not being run: PHPUnit expects a single test class per file
   - move classes to separate files
