Keymap: Arkag Userspace and MechMini2 Layout (#3958)

* deleting arkag branch, forcibly moving changes over to master

* fade_color function added, not tested

* added half functions some stuff

* surround_type function implemented and working.

* added flashing function and removed fading, flashing supports infinite flashing along with controlled number flashes

* added a fade state machine and functionality

* build optimizations, changed fade to bounce between bounds rather than roll over, added a HALMAK layout

* changes to sleep breath function, changed how I will switch to HALMAK

* support for halmak added

* support for activity detection added, condensed fading and flashing state machines, removed support for HALMAK and COLEMAK because arkag is stupid

* changed sleep and inactive behaviors, now the color shifting reverses on state change, yay! save_color and reset_color are made to enable layer color changing to look cooler.

* reformatted some if statements in state detection

* changes to force fade to pause on boot, or plug in.

* Attempting to move over to userspace, pushing to repository for help

* userspace stuff....

* userspace stuff....

* layout changes, working userspace,

Removed left side shift and replaced it with a MT() for LSFT and SPC. Userspace seems to be working properly now! HURRAY

* Layout change

Removed space/shift and reset modifiers to what they were originally. Added homerow modifiers.

* Removed excessive tabs in files

* Moved mods on homerow around...

* changes recommended by @drashna
