Changes requiring user action

Key Override Introspection

Changes were made to key overrides in order to hook them into the keymap introspection system.

Key override signature changed from:

const key_override_t **key_overrides = (const key_override_t *[]){

to:

const key_override_t *key_overrides[] = {

The list of key overrides now does not need to be NULL-terminated.
