m_nocreate improvements

[H7-25]

i think this improvement should be useful :

• an option to don't affect registered users
• an option to don't affect registered channels
• when telluser="yes" is set send the reason instead of the default message "You are not allowed to create channels"

* an option to don't affect registered users

I'll try to add something in a per X-line manner rather than a global config setting. I purposely left this kind of option out as the default supplied modules for oper-only or registered-only channel creation already cover this.

* an option to don't affect registered channels

I don't think this is possible. Until a channel is created, the IRCd has no knowledge of it regardless of what services knows. Maybe there's some fun trickery that can be done, but I'd expect this to be a no-go. Ideas or obvious solutions that I'm missing are always appreciated.

* when telluser="yes" is set send the reason instead of the default message "You are not allowed to create channels"

This is easy enough; I'll probably add a configuration option for a default or to use the per X-line reason.

This is taken care of with: https://github.com/inspircd/inspircd-contrib/commit/e94c0b1b40a9ecc9234a7f54c1477f30475d7b33

• If <nocreate:reason> is not empty it will be used, otherwise the individual reason will be used. This only applies when <nocreate:telluser> is enabled.

• Prefix a full nick!user@host mask with U: to match only unregistered users.

I'll regen the modules list after I update all the helpop examples in my modules.
