Second major commit to code merging and updating, still non-functional

Botconfig:
- Added settings for various commands to be allowed in certain channels
- Copied over all variables from settings/wolfgame
- Added a bunch of variables, most not implemented yet
- Removed the arguments for launching

Wolfbot:
- Changed functions to check for settings elsewhere

Decorators:
- Added handle for both op_only and admin_only
- Renamed all 'var' to 'botconfig'

Common:
- Add check for case-insensitive channel name
- Add checks for various commands to be allowed or not

Settings:
- Make the file hold defaults
- Add arsonist-related variables (not implemented)
- Add check to allow or not !nolynch
- Add "pyromaniac" template settings, which is to the arsonist what the
sharpshooter is to the gunner
- Modified channel rules (this is default, can be changed anyway)

Wolfgame:
<diff too large to show, will edit when commited>
