Initial version release of incobalt's Roleplay Chat.

The main feature of this mod is a distance-based chat to keep chat localized to an area. The mod also adds commands to simulate raising (/shout) and lowering (/whisper) your voice, and an admin command to send a message to everyone on the server (/broadcast). Chat color codes are also implemented with &, but this is restricted to a configurable permission level.

Also included is a missive system that replaces Minecraft's /msg command. Missives greatly restrict long-range messaging to a time-based system that optionally uses resources.
