- Immediately displaying the new channel info when switching channel groups.
- Moved the main program loop variables further up to allow compilation with
older compiler versions (thanks to Marco Schlüßler for reporting this one).
- Now calling pthread_cond_broadcast() in the desctructor of cCondWait and
cCondVar to make sure any sleepers will wake up (suggested by Werner Fink).
Also using pthread_cond_broadcast() instead of pthread_cond_signal() in
cCondWait, in case there is more than one sleeper.
