* Functional stats panel

Needs more check, as i've only tested it on altlinux

  this was broken when the video file name included its directory name
  (for instance "vlc dir/file.avi")

* Fix item add in RC

Several people use it and nobody complain it was broken.
Besides, some stuff seem not to work without it.

  this needs to be tested

* more synchronization with playlist and input threads
* new libvlc functions binded

* video.c: added 1 release object in GetVout
* input.c: added libvlc_get_input_thread helper

* video height/width retrieval
* input playing status check

* Add notify plugin
