initial commit: added a custom built vlcj library that includes compile test output so we can use the examples in them

added VlcjPlayer, derived from TestPlayer in vlcj
VlcjMediaPlayerController will actually tell the VlcjPlayer to play and pause
VlcjPlayer is just a gui wrapper around an EmbbededMediaPlayer that we added streaming support to
VlcjPluginActivator just natively draws and starts the VlcjPlayer window on jitsi client startup right now

todos: clean up encapsulations, maybe move things to impl and service packages, we'll see if we get to that before we switch to hacking on videobridge
Merge branch 'master' of github.com:jitsi/jitsi
