fixed computer top texture when on; not sending item tag info to clients anymore (usually only the associated node's address. generally nothing the client needs to know); removed neighbor logic from item component nodes since that is taken care of in sentToVisible now; improved screen rendering performance a bit by caching the display list and updating it when the screen's display changes and not rendering at all when too far away or looking at the screen from a direction where it's impossible to see the text; added some classes that guava needs to compile in scala (only needed at compile time afaik)
