Felix Kauselmann be547081f2 Fix huge memleak in server code caused by thread pingpong fix.
Stopped QThreads don't process events, so cleanup signals get lost.
Prevent this from happening by keeping the threads alive and the comic
inside the thread (as we already do in the viewer). Cleanup happens by
connecting the comic's destroyed() signal to the thread's quit() slot.
