This includes a feature to ghost, which simply calls the ghost feature
of the actual nickserv. Same goes for group, recover and release.
These are called by simply doing /msg *nickserv ghost <nickname> etc.
The changes made actually explain themselves when doing something like
/msg *nickserv help. This is really just so we can be lazy and execute
nickserv commands that require a password without knowing the password
ourselves.
