Qt4 - Volume Icon updates NOT in an TIMEOUT function, which is called very often. Redesign only when needed.

Makes services_discovery option strictly load the given module (i.e. not use a fallback module if the one specified isn't available)

Sets default icon to high

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.
