[Pkg-kde-extras] taskjuggler desktop file

[Fathi Boudra]

i asked chris Schlaeger about the desktop file :

> 'ProjectManagement' is used by SUSE, so I'd like to keep it.
> I'm fine with adding Office as well.
> Would Categories=Qt;KDE;ProjectManagement;Office 
> be ok for Debian?

so i'll commit the changes.

cheers,

Fathi

PS: package use kde.mk now
