Redesign tx_mmforum_usersearch.php script
The tx_mmforum_usersearch.php is responsible for the ajax autocompletion feature when writing new private message. At the moment, this script is a standalone script that includes the localconf.php and connects to the database on its own, and because of this becomes very error-prone (like e.g. by the use of undefined constants in the localconf.php). Therefore, this script should be replaced with one using the TYPO3 Extension-ID mechanism.
[~TASK] The RSS feed feature is now documented in the official maunal (fixed #4720)
[~TASK] The messaging user search script was redesigned (issue #5932)
[~TASK] Cleaned up TCA. Avatar upload now respects TCA setting for max file size (fixes #4129)
[#BUGFIX] ALT- and TITLE tags for smilie buttons are now set correctly (fixes #2071)
