Subject: We now have keyboard support!!!

I also added the WAI instruction, which puts the thread
that executed it, into a catatonic stat, where it can't
do anything, until an interrupt occurs.

I will be starting work on GFsuX next.
I also might start work on SuBAsm, the
Sux Bootstrapping Assembler.
