* @author Patrick Cool < patrick.cool @ UGent . be > , Ghent University: code cleaning
* @abstract The task of the internship was to integrate the 'send messages to specific users' with the
* Announcements tool and also add the resource linker here. The database also needed refactoring
* as there was no title field (the title was merged into the content field)
* @package dokeos.announcements
* @todo make AWACS out of the configuration settings
* @todo this file is 1200+ lines without any functions -> needs to be split into
* multiple functions
