- Server enumeration, with handlers for BURST (introduction to uplink), SERVER (introduction of uplink's other leaf servers), NICK, and SQUIT (closes#2)
- Store UIDs instead of nicks in the user database - this makes the protocol a lot easier to work with.
- PLUGIN SUPPORT and COMMAND HANDLING, wow!!!!!!!
- Restructuring of files so that there's only one protocol module (anything else is too much to maintain for now)
- Split protocol things into utils.py
- Bugfixes: don't go into an endless loop of text spamming when the remote host closes the connection!
