src/control/media_instance.c: Don't wait to have modulo something, to forward the time, that could be crazy.

* Implement MediaInstancePositionChanged and MediaInstanceTimeChanged accurately.
control/event.c:
* Register the all event types.
* Don't strdup() in libvlc_event_type_name().

media_instance.c: Fix the position callback to retun the time. (Next time, we'll fix it to return the position).

MacOSX/Framework/VLCTime.m: Fix a segfault because of a missing retain. Create a real null time. Code simplification.

* add a 'graphite' button set including the facilities to switch the theme at runtime (closes #1379)

MacOSX/Framework/VLCLibrary.m: Default the use of the opengllayer video output module. Don't be verbose by default.

Only the file access uses this, but I don't like "wild" callbacks into plugins.

* adapted the wizard to use the RTP stream out module instead of the removed RTP access out. Please check the other interfaces...

small fix for http-streaming, don't set b_die to true in beginning if
object is alive.

Fix segfault when Connect() returned failure and fix memleaks. Make sure live555 modules exits while in Connect() if vlc is asked to stop.
