Player: new -a option to enable alpha on frame buffer.

A new option '-a' can be passed to the blenderplayer. It forces the
framebuffer to have an alpha channel. As the background color is applied
with 0 alpha, ImageViewport will return an image with transparent
background (provided alpha is set to True on the ImageViewport object).
This is useful in combination with DeckLink to generate a key frame
with transparent background.
Without the -a option, the frame buffer has no alpha channel and
ImageViewport always returns an opaque image, no matter what.
This should be working in Windows and Linux, but only Windows is tested at
present.
Note that although the frame buffer has alpha, the player window is still
rendered opaque. Transparency of the window is possible using the
'compositing' functions of Windows and the code is already there for that
(look for WIN32_COMPOSITING) but is not enabled because 1) it doesn't work
so well 2) it requires a DLL that is only available on Vista and up.
