* Add satan keymap: HHKB-alike based on dbroqua's, with mouse functionality and without LED functionality
* move mouse layer to DOUBLE_HOLD, add UTIL layer for TRIPLE_HOLD
- UTIL layer
- currently has "RESET" key and nothing else.
- functionality otherwise covered by bootmagic should go here
- small bugfix: dispatch of [QTY]_HOLD should be based on range tap count
falls in, not exact count.
