*: initial commit

This is largely ripped out of Eon to try give a reusable
scaffolding for accelerating SDL-based simple game development.

I expect there to be future commits adding more configurability
like a means of influencing which flags are passed to SDL_Init(),
e.g. if you have no need for joystick support, don't pass in that
flag, and libplay won't pass it to SDL_Init() and do the joystick
opening/mapping dance, etc.
