Add event bindings.

So far, only window and keyboard events are handled.  More to come in
future patches.

This patch adds a *ton* of constants that I'm not going to mention in
this log because it would be too damn long.

* sdl2/bindings.scm (sdl-poll-event): New procedure.
* sdl2/events.scm: New file.
* Makefile.am (SOURCES): Add it.
