Smallish overhaul of Auto-Shift feature (#67)

* Fix edge case when using One Shot Layer with Auto Shift, and it not triggering the cleanup * Remove junk code (no longer used) * Replace `(un)register_code` calls with `tap_code` where appropriate * Fixed up Switch check to be more readable (less verbose) * Simplified modifier check (if it comes back non-zero, there are mods) * Add additional function calls for autoshift settings * Made all variables static, since there are function calls to get their status * Fixed up documentation
