skins2: implement recording and next-frame

This patch adds the following keywords for skins developpers :
      - vlc.canRecord      (boolean / refers to can-record)
      - vlc.isRecording    (boolean / refers to record)
      - vlc.toggleRecord() (function / toggle recording)
      - vlc.nextFrame()    (function / next frame)
