patch for adding sdl keyboard support

[Timmy Douglas]

Keyboard events weren't being generated so I traced the problem to
being that it wasn't implemented yet. So I added some functions.


Could someone give me feedback on the questions I asked in my last
patch and that question about the root trait graph? I'd like to hear
something before I start to write code to randomly pass keyboard
messages to SceneElements. Thanks.
