Admin console for the server

[beatgammit]

Should allow for basic settings changes and admin tools on the server.

Possible settings include:

• compression algorithm
• custom functions (database interface, custom compression algorithm)
• custom resources (requires restart)
• location where files are saved
• port (requires restart)

Admin tools:

• server load
• error logs
• active clients
• bandwidth throttling (per client and global)
• send message to clients (over Web Sockets)

I've pushed a basic admin console to the branch adminConsole. The admin console supports:

• CPU load, calculated over 2 second periods
• RAM usage, calculated over 2 second periods
• Ability to change the port without restarting the server
• Ability to change the document root (not tested)

The admin console can be prettified. When that's done I'll go ahead and close this issue.
