Also delay view creation in constructor after the title label has been created

This enables usage of vlc extension in Lunettes.

This needs to be splitted in a separate files.
VLCDialogGridView still suck, and won't place items as we would expect them.

It fixes zoom settings at the core level (partially close #3245).
"zoom" cannot be removed as it provides a list of choices while "scale" is
a free value. The names aren't great, but that can wait.

The zoom parameters need to be taken into account as the window
can be resized.

With wine, this module goes through the error procedure, but forgets to
deallocate the progress bar (stuck to 80%).
This patch simply cleans it up so that vlc can still be used satisfactorily.
(an error message is also issued anyway)

Should fix issue on not scrolling to current item when it changes in iconView

allows only to control some important options of the AtmoLight module, which control the color calculation.
Hardware setup has to be done inside the normal video filter setup.

- 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

Add album name and break long lines.
