Description

Here's a couple of new configuration features for combos.

COMBO_MUST_PRESS_IN_ORDER to force combos to only activate if the keys are pressed in the same order as they are defined in the combo's key array.

Per combo configuration can be modified by defining COMBO_MUST_PRESS_IN_ORDER_PER_COMBO and defining
bool get_combo_must_press_in_order(uint16_t combo_index, combo_t *combo, uint16_t keycode, keyrecord_t *record) function in which you choose which combos require the correct key order.

This feature even allows multiple combos from the same keys. For example on qwerty layout, JK can produce / and KJ can produce \. Just define two combos using the same keys but put the keycodes in reverse order for the other one.

COMBO_SHOULD_TRIGGER and its companying function bool combo_should_trigger(uint16_t combo_index, combo_t *combo, uint16_t keycode, keyrecord_t *record) enable disallowing combos to be activated when you choose so. For
example on certain layers, or when a timer is running.

Submodule changes need to be rolled back.

The one time I think git commit -a is fine...
