with actual system library (seems to fix weird compilation problem with
flac and theora builtins)

(avoids spamming the MBONE with incorrect private streams)

May fix builtins recompilation (theora, flac...)

(this commit obviously breaks binary compatibility - clear your plugins)

* new psychedelic FOSDEM demo filter. enjoy :)
* misc changes          

tree configuration is modified

as it did never worked properly, if at all with these
(you should use libtool to build a shared libvlc instead)

- accessible by double-clicking on the time-counters and through a menu-item in "Playback"
- the class of the time-counters is VLCTimeField now, because we need to fetch the mouseDown-event. There are no further changes compared to NSTextField.

Add toggle_mute

to fix that.
