Add keyboard patch from Andrew Warkentin <andreww591 gmail com>

I fixed the keyboard in FreeBee. I looked at the keyboard driver source available on a few sites, and it appears that BEGKBD/KEY_BEGIN_KEYBOARD is only supposed to be sent after the end of mouse data, and that KLAST/KEY_LIST_END is not a separate code, but a flag that is set on the last non-KALLUP/KEY_ALL_UP code in a list. I have attached a patch that implements these changes. I have also attached a patch that adds the 60Hz timer interrupt (I'm not sure if it's totally correct, though, since the cursor blinks rather slowly).
