* Set Dvorak as the standard base layer
* Remove unneeded includes
* Remove custom handling for Quake 2
Have now rewritten my in-game configuration to use Dvorak mapping instead of QWERTY, which means I don't need any of this stuff.
* Clean up comments in KC60 keymap
This is a place for users to put code that they might use between keyboards. If you build the keymap mine, /users/mine/rules.mk will be included in your build, and /users/mine/ will be in your path - keep these things in mind when naming your files and referencing them from other places.
