[Open Assets] Grapple points 2.0

Added few actions to customize grapling behavior! They will be explained in "Adding graple points" spoiler

Somehow i forgot to add more player starts on the map so here they are

Small update that adds a tip (only appears once) when map with grapling lua loaded.
Also changed map id to MAPKK, since MAPAS is taken, according to spreadsheet in kartkrew discord.
There are no gameplay/map layout changes.
