Made the chat global instead. Working on making trading.
Merge branch 'master' of https://github.com/serprex/openEtG

Conflicts:
	server.js
Finished the trading system. Will probably expand it more later, but this works.
Added request messages in chat when another player wants to pvp or trade with you. They do not seem to work perfectly, usersock does not always seem to have all values?
Deleting the entire sockinfo object isn't advisable (ie you're going to crash the server) so encapsulate trading info inside a trade object that you can delete after instead
