* gui behaviour change: the textfields are no longer disabled if another protocol is enabled through the knobs. the user can click the fields now to switch the protocol. I'm unsure whether this could and should be done in the disc tab as well. closes #914

* hide the fspanel if VLC looses its front app state in fullscreen mode (by using the app switcher, etc.)

Fix Win32 implementation

* Make it possible to extract any color component from the video. (Red, Green and Blue are still hardcoded) Example: ./vlc ~/media/Muse-Concert.mpg --video-filter "extract{component=0xFFFF00}" will get you the yellow stuff.

 * New color extraction video filter. Can be used to extract the Red, Green or Blue component from a video.
 * Add stuff about motiondetect and extract in the News (even though motiondetect isn't finished)

Rewrite motion detect filter. It currently draws a white rectangle arround moving objects (on fixed backgrounds). I still need to add code to make it possible to trigger an action when movement is detected (i.e. a VLM command to start recording).

Fix size of preference tree items

* Added some comments
* Set the b_pausable flage and remove the b_fade/b_stop flags from the dvbsubs.
  They are ephemer and if you need these options set, then figure out another way.
