I was always bugged by the fact that (center of (entire map region)) returned a position 1 tile off from the actual map's center, and turns out the entire map function intentionally returns a region offset by 2 tiles? Not sure what the reason behind this is

Add 4 functions for incrementing player/entity attributes. Usage:

increase (attribute) of (player) by (value)
decrease (attribute) of (player) by (value)
increase (attribute) of (entity) by (value)
decrease (attribute) of (entity) by (value)

Also move 'comment' case to the top so it breaks out of the switch early when encountering a comment instead of testing the 200+ cases
