Macro update, roam mon annotations

Updated map and mapgroup macros to get around an rgbds bug.

Legendary beast locale handling annotated and relabeled.

Added a new constant NUM_ENGINE_FLAGS for use in the EngineFlagAction function.  This will make it easier for modders to add or remove engine flags.
