Refactor SelectSocket and minor net cleanup

This commit refactors SelectSocket from having a socket.socket member to
inheriting socket.socket and adding a poll method to it. This simplifies
confusing code throughout net (ex no more self.sock.sock.something).

Also fixes a couple minor things throughout the plugin and does a little
bit of code cleanup
