Merge pull request #20 from JacobLeach/backspace

Backspace works
Added the basic code for simple ANSI Control Codes.

Have not yet tested. Need to update the keyboard driver first. This is
also just for fun and could be a terrible failure. It is also not the
best way to go about doing this but that's whatever.
Added support for escape.
Merge branch 'driver_keyboard'
Merge branch 'master' into console
Added support for two ANSI control codes.

Both CSI F and CSI E both work. Also had to change it so that any
non-supported ASCII characters from the keyboard driver get turned into
null. Not the best but it works for now. :(
