loncommom.pm: Inserted the functions clean_symb() and get_annotations() from adannotations.pm
lonmenu.pm: Fixed the Bug 1736: Check whether a user already made an annotation for the resource. In a case of an annotation, the icon is replaced by an other icon. This does not work with the remote control and the display option "buttons and text".
