Fixes:

Fix UHK 80 USB power transitioning issues. The UHK 80 should now resume from sleep without reconnecting USB.
Fix variable interpolation when double quotes are not used on the UHK 80. SMARTMACROS:PATCH
Fix key chatter on the UHK 60 when letters are typed while mouse-keys are being used.
Fix warnings regarding the switchHost macro commands on the UHK 60. SMARTMACROS:PATCH
Fix "Invalid abbreviation length" produced when saving a configuration that removes currently active keymap.

Battery management:

Make battery readings much more accurate and consistent.
Add power saving mode.
Disable key backlights and dim the OLED display in power saving mode.
Blink the battery percentages of the halves that are in power saving mode.
Implement battery health optimization mode for stationary use.
Implement proper sleep mode. S+F keys together wake up the left half, J+L keys together wake up the right half.
Change battery percentage indicator: use lightning icons instead of + signs to indicate battery charging.

Configuration changes:

Add set battery.chargeLimit { full | optimizeHealth } macro variable. SMARTMACROS:MINOR
Add configuration settings for extending battery life and limiting key backlight during charging. USERCONFIG:MAJOR
