> Implemented Channel System to replace @main. See tid:80999 for full details. (Hercules 7ec1e8f, 1e87c09)

* Adds @join and @channel commands to manipulate chat channels. (see doc/atcommands.txt)
* Speak in a #channel by sending a whisper to #channel or binding your global chat to the channel (@channel bindto <#channel_name>).
* Automatically join local map channels (#map) and guild ally channels (#ally), with mapflag 'nomapchannelautojoin' to disable the channel for a map (optional).
* Allow users to create private channels if 'allow_user_channel_creation' is true.
* Set default channels, text colors, and other settings in conf/channels.conf.
> Other changes:
* Improved overall guild processing/lookup by creating a cached guild state.
* Fixed a bug where equipping a garment would override costume garment.
* Removed clif_message and merged it with clif_disp_overhead, since both use the same packet.
