LukeMS's port of the PyGame time API to sdl2
@LukeMS has this added to his personal sdl2 repo on GitHub, but hasn't offered the patch upstream. Enough people seem to want it that I've decided ti offer it as a PR. I didn't take time to write unit tests for it, sorry. Closes marcusva/py-sdl2#168.
I've stopped using this code, instead preferring to let my update loop run as often as it does and keep track of elapsed ticks. When enough have passed for something to happen, I do it. But this API provides the simplicity of the PyGame API in this respect because it duplicates that API pretty exactly.
@iKarith Thanks so much for the PR! Sorry for not getting around to this sooner, I've been super-busy with various time-sensitive academic projects. I'll try to review this properly this week.
