Release Candidate 1

- (hopefully) fixed a bug in the SqlConnector class, which would
generate "There is already an open DataReader associated with this
Connection which must be closed first" exceptions. May cause a
significant negative impact on performance though.
- Now loads all IRC and SQL settings from a settings file
- Fixed a potential security issue and bug where single quotes wouldn't
be escaped properly
- Finished the command system
- Added a few test commands
- Fixed an issue causing profanity counts to be updated globally instead
of for each user independently
