Various fixes.

For this update, I originally planned on implementing the session system, but I didn't really managed to finish it as I planned. I am going to instead add this multi-session part with the improved title generation. But I have done various improvements on other stuff.
Changelog:
*Made the game save the open servers and resuming computers lists, using nbt.
*The connections are now also saved using nbt. Minestuck can still load saves from the old format.
*Crocker sporks works now! They are using a not too good method to do more damage as fork, but I don't really know how to use attributes for doing so instead.
*Suggestion: Fear no anvil sometimes slows the target. Feel free to change or remove it if you disagree with something about that, I don't mind. (but if we keep it I must say that it would be good if it acted like more like a critical hit)
*Smoother randomizer on vrillyhoo.
*Fixed a resume bug in the SkaianetInfoPacket.
*Made SkaianetHandler also check if the server is active (open or resuming) before trying to do something.
*Improved computer message even more.
*Using a perfectly generic object punchcard in a totem lathe returns an uncarved totem instead.
*And possibly other stuff I forgot to add in this list.
