Removed ratelimit handling, command adjustments

* Instead of using RateLimit, the ChannelFlood channel mode (+f) will be used instead so as not to cause problems with things like joining channels in the future, which kicks the user instead of ignoring messages. When kicked, the reason is now displayed if it exists, as it should be.
* /help is now available for commands, and an error isn't caused when a command that requires parameters doesn't have any.
