Adds bpy.app.sdl to expose SDL version information. When SDL is not available on a Linux system, certain Blender features are silently disabled (like joystick support in the BGE). This change is the first step towards making it more obvious why something isn't working. SDL information is exposed to Python via bpy.app.sdl, in the same way as OCIO and OIIO information is exposed. Generated system-info.txt contains SDL loading method (linked or dynamically loaded by Blender) and SDL version number.
