enhanced & corrected AtmoLight filter module

enhanced & corrected AtmoLight filter module
- added more thread locking/synchronization, to avoid potential risk of race conditions
- changed the option to choose the output device
- added support for MoMoLight (http://www.ambilight4pc.com/momolight/momolight.html)
- added support for a simple serial DMX (255 channel) controller
- added support for Quattro Atmo Light (allows to use four separated classic AtmoLights, as one virtual AtmoLight)
- changed the way color packets are passed from AtmoExternalCaptureInput to AtmoLiveView useing a queue object (instead of a unsynchronized global variable)
- renamed some options inside atmo.cpp to meet the requirements from the video effect dialog widget (later commit)
- changed the way to define the zones for image color extraction (because the number of zones isn't longer fixed to 4 or 5)
- removed the need to copy some .dll as bridge for the external AtmoWin into the VideoLAN folder, try to load the dll from the same folder like AtmoWinX.exe
- do not a complete fade out, if the filter processed a low number of frames and gets stopped (keeps VideoLAN quick responding, if switching through deinterlacing modes)
- added a debug option to see which pixels are used for color computation (just for fun)
- added more infos to README.txt inside the source folder
