Key binding definitions.

Regular keycodes go up to 255; special keys start at 256, and can be
calculated by adding 256 to the GLUT key value in glut.h.

All Nasal code in this file lives in a common Nasal namespace __kbd.
All <nasal> blocks on the top level are executed in the order from
top down before the key bindings are parsed.
