Handle special keystrings case-insensitively.

Browse Source 
Load all special keystrings (e.g. <ctrl-a>) into memory as lowercase,
and automatically lowercase any special keystring given to bind/unbind.
This prevents <ctrl-a> and <Ctrl-A> from being treated differently.

Resolves #816.
Also resolves #1544 (dupe).
