Gives mod makers a set of functions to safely apply player physics overrides.
Add a named override which can be used to add or subtract from speed, jump and gravity effects, or set custom overrides for "default", "min", "max", "force".
pova.add_override (player_name, item, def)
Remove the override for the item named:
pova.del_override(player_name, item)
Returns a table containing {speed, jump, gravity} setting for the item added:
pova.get_override(player_name, item)
Calculates and sets new override instantly:
pova.do_override(player)
