Fix up the bugs from last night's hell netgame.

* The tab and intermissions rankings...
	* ...now have parity in behaviour!
	* ...now properly handle player counts over 8, and no longer supports player counts over 16!
* The Item Arrow in Battle...
	* No longer develops any extremely stupid bugs due to Orbinaut sprites that makes all objects in state S_INVISIBLE develop <!>'s! (Ask me about this if you're curious as to how it affected everything else too.)
