BlackBerry and Android -Added ability for developer to choose OpenGL ES version (2.0 or 3.0) via glutInitContextVersion (only the major version is used)

Browse Source 
BlackBerry specific
-Added better documentation on required window bit depth for BlackBerry.
-Modified screen format picking so it will choose either RGBA8888 or RGB565 instead of always using RGBA8888
