forked from extern/egroupware
reworked link classes:
- new public egw_link class, which has only static methods and can NOT be instanciated - depricated bolink class, for existing code instanciating the bolink class in $egw->link - new method and application hook *titles* to retrieve the title of multiple entries of an app in one go - new method *get_links_multiple* to retrieve all links of multiple entries of an app
