2015-10-21Add sdl_hints:add_callback/3 functionLoïc Hoguin
This also sets up esdl2 to start accepting callbacks. The module/process esdl2_callbacks must always be running for that purpose, so esdl2 was made an OTP application instead of a simple library. Implementation of the rest of SDL_hints will follow in subsequent commits.
