Bug #0000268: Code Cleanup in 5.2.x branch
- fixed path to s.gif in FCKEditor file browse dialog
- same kModulesHelper::getModules method is used during installation and in admin to get modules, that can be installed
- fixed some PhpDoc comments, that were not matching their method declarations
- moved duplicate request processing detection into Request class (from kApplication class)
- replaced aliased function calls with original function calls
- fixed some grammatical errors
- most of file system interations (where folder is scanned for a specific content) are replaced with DirectoryIterator (from SPL)
- removed duplicate tags from FckTagProcessor, since their copy from fckFCKHelper class was used
