Mass-restructuring of bot configuration.

This is the major chunk of the work i outlined in #53. It should make updating and maintaining Showbot easier both for you and other people that want to use the project.

All of the major bot configuration has been reduced down to editing cinchize.yml and .env. Been running most of these changes live to test them out without any issues that weren't PEBKAC.

The only completely untested section is the migration of the backup.rb settings to .env, so you may want to verify that works. :)  Everything else is pretty much explained in the commit messages and outlined in that issue, i'll post there listing what's left to do and hasn't been included in this MR.
