Qt4 - Fullscreen button should work now. hasVideo() does not work, so force the activation of related buttons.

Qt4 - Audio/Video order fix in menus. Changes MediaInformation shortcut to Ctrl+I. Will not remove Ctrl+J for codecs since this is one of the most asked question.

(it was only used internally by the RTP sout).

Only now there is one per track rather than one per client per track.

small typo to fix port-audio/video sending.

Patch by  Hannes Domani

Qt4 - MainInterface, implement the feature request to show elapsed/remaining time in the statusBar() through a menu.

Fix play/pause toggle
Removes 2 unused signals

Qt4 - Media Info. Re-add some info for DVB. Clean the in_Edit state that was stored two times in different classes.

and fix a few minor leaks

This saves:
 - one malloc() per packet per client } due to
 - one memcpy() per packet per client } block_Duplicate()
 - one mwait() per packet per client, and
 - one thread per client per track

So it should really help scale RTSP broadcast up.
However, in its current state, it removes the pts synchronization,
which might not be such a great idea. I will re-add it later.
