Main - Added new handling for admins per channel with appropriate checking throughout the commands.
Main - Finished new admin structure. We now support admins by channel and respect them as such. We currently read every admin that exists and assume they also have admin power to the bot. Also added a check for the bot to see if it's op before trying to change the topic. Updated the example config file to support these notions as well as adding support for a server password.
Merge branch 'admins' -- merging in updated admin support.
