include/vlc/mediacontrol.h, src/control/mediacontrol_audio_video.c: implement get_/set_rate and get_/set_fullscreen

linux also (I do no quite know the current status, but it works for me this way at the moment).

* add "make nice" in modules to call ./compile

* malloc with NULL check
* file extension check
* check if a demux was forced
* try peeking, and check what we poke
* init standard demuxer fields
* create packetizers

bindings/mediacontrol-python/vlcwrapper.py: make the tree() method return a string rather than print it.

* handle play/pause status

* adapted the extended panel to the latest video filter changes and re-designed the interface a bit (by introducing some additional strings and moving the invert-option to the adjust image section, etc.)
* src/video_output/video_output.c: small fix to insert filters on the fly

Exemple: --video-filter "adjust{hue=180}:wave"
For the moment, the video filter2 filters are applied *before* subpicture filters.

That has been annoying quite a bunch of users[1] including buildbots
and myself.

- currently loaded through rightMouseUp because rightMouseDown, etc. don't register any NSRightMouseDowns. If anybody got an idea why, I would be willing to change this of cause, since the current way is quite slower in the user's experience.
- the Snapshot item doesn't work yet (it triggers the fullscreen-event)
- localisation support is complete

Any comments and wanteds for further items are welcome :)
