* Initial Commit Port from xauser's jetfire code. Does not compile yet * fix up keymap from uint8 to uin16 * update rules file to contain custom matrix * Good stopping point Still lots of compile errors but I'm getting there. * fix a few more compile errors * move a few functions around to help with compiling * Finally got it all to compile * Get rid of that old KEYMAP macro * edit readme * Put my name everywhere and some minor code clean ups * start to remove that kc nonsense * fix keymap compilation issues * add reset key info * better human readable formatting * match the duck default layout * add confgurator support * clarify reset key * might be a good idea to use the correct pin * get the riight keycode for RGB * include an ALL layout * I tried to fix the formatting....sigh * add functons to ensure Configurator compile-ability * move jetfire to duck directory * Moved and renamed things as per Drashna's PR comments as his back was hurting as he reviewed this
