config.h: add licence

simplify rgb lighting

set colors using post-init hook instead of relying on eeprom.
previously keyboard would load colour from eeprom, and if different firmware set
it to a different one, it would stay as is, which is why i added the eeprom clean button.
now there's no need to touch eeprom at all.

fix mousekeys order

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
