before the $var. Changed some other types to match the more common
spelling. Makes beginning of some text in captial.

Broken since introducsed in r10810 almost six years ago.
This proves that the exception in message caches is valid and covers errors.
Tested that exception is no longer thrown.
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.
* Removing span from Language::translateBlockExpiry.
* Adding span conditionally in LogPage::actionText, and using appropriate language (interface and content).
* Removing translate parameter from LogPage::actionText: no longer needed, always translate.
