wtf, button 2 is not middle, but right. makes no sense, but whatever.

various tweaks

updated copyright
removed TTY(7)..TTY(12), but don't know what to do with the remaining empty space.
added mousekeys, will see if it is useful or not.
optimized numlock indicator (i have no clue why i did it through hsv)
added replies to comments from future me :)

restructure as external userspace

keymap: swap caps lock and escape, use macros for indicators
