Updated the linkage between the NanoTrasen IRC bot and the server.

- Server will now send adminhelps to the admin channel, with information if there is no admins online.
- Server will inform the admin channel if the last admin online logs out.
- When a round ends, the server will alert the main channel, supplying some statistics.
Additionally, laid the groundwork for an external scripts system.
This is fully configurable/togglable in the config.txt file.
