MRC Enhancements: Server Stats & additional tweaks

• MRC-Connector now makes requests for server stats every 20 seconds. These stats are displayed on the MRC-Client screen as well as stored in a file named mrcstats.dat for display elsewhere. See readme.txt for more info.
• Updated CTRL-A color code notation all throughout.
• Updated param handling in the handle_message function.
• Duplicated /msg command as /t, which is the standard direct/private message command on Mystic clients.
• Message timestamps are now formatted as HH:MM rather than standard javascript locale time.
• Removed the nick list divider.
