* Split $wgFixArchaicUnicode into two separate variables, one for Malayalam and one for Arabic
* Clarified documentation and switched them both on by default
* Removed accidentally added variable LanguageAr::$normalizeArray
* Added $wgFixArchaicUnicode, which, if enabled, converts some deprecated Unicode sequences in Arabic and Malayalam text to their Unicode 5.1 equivalents.
* Added generateNormalizerData.php to generate the relevant data files. Added the generated data files also.
* Made most things call the new wrapper method $wgContLang->normalize() instead of UtfNormal::cleanUp(), so that Unicode normalization can be customised on a per-language basis.
* Added some generic support for conversion tables to Language so that subclasses can easily implement these kinds of transformations.
Doxygen documentation update:
* Changed alls @addtogroup to @ingroup. @addtogroup adds the comment to the group description, but doesn't add the file, class, function, ... to the group like @ingroup does. See for example http://svn.wikimedia.org/doc/group__SpecialPage.html where it's impossible to see related files, classes, ... that should belong to that group.
* Added @file to file description, it seems that it should be explicitely decalred for file descriptions, otherwise doxygen will think that the comment document the first class, variabled, function, ... that is in that file.
* Removed some empty comments
* Removed some ?>
Added following groups:
* ExternalStorage
* JobQueue
* MaintenanceLanguage
One more thing: there are still a lot of warnings when generating the doc.
