Highlander: Clean up code style, indents and delete useless old comments

--------------------------------
-- HIGHLANDER / HOGS OF WAR
-- by mikade
--------------------------------

-------------------------
-- ideas for the future
-------------------------
-- add structure
-- allow switcher, resurrector
-- nerf teleport
-- balance weapon distribution across entire team / all teams
-- add other inequalities/bonuses like... ???
-- * some hogs start off with an extra 25 health?
-- * some hogs start off poisoned?
-- * some hogs start off with a rope and 2 drills but die after their turn?

--[[ Multiple weapon usages.
This is a bit tricky to explain.
First, remind yourselves that hogs can never hold more than 1 of the same ammo type.

This param changes how ammo will be restocked after killing a hog if you
already owned this ammo.
Basically this is about if you can use the same weapon multiple times in a
turn by killing enemies in a clever way.
We need to distinguish between your current inventory and the “reset inventory”,
that is, the state to which your inventory will get reset in the next turn.

No Multi-Use (default):
	If you kill a hog who owns a weapon you currently have in your reset inventory,
	but not your inventory, you DO NOT get this weapon again.

Multi-Use:
	If you kill a hog who owns a weapon you currently have in your reset inventory,
	but not your inventory, you DO get this weapon.

Example 1:
	You have a ballgun, and use it to kill a hog who also owns a ballgun.
	No Multi-Use: You will NOT get another ballgun, since it's in your
	reset inventory.
	Multi-Use: You get another ballgun.

Example 2:
	You have a grenade and a bazooka in your inventory. You use the bazooka
	to kill a hedgehog who owns a grenade.
	In both ammo limit modes, you do NOT win any ammo since you already have
	a grenade in your inventory (not just your reset inventory), and the
	rule “no more than 1 ammo per type” applies.
