hastodo — Check if top-level to-do exists.
hastodo(QString taskname) is a D-Bus call that
looks for a of the given name. If found, it returns the
iCalendar UID that identifies that to-do. If not found, it returns an empty
string.
The iCalendar file that KTimetracker currently has opened is the file that is searched. All to-do trees are searched, not just top-level to-do's. If more than one to-do has a matching name, the first one found is returned.
