modules/protocol/unreal4: Adjust default usermodes for service bots to include TLS-only & hide ircop usermodes

[alicetries]

This adjusts atheme's services bots to include +z and +H as part of their introduced usermodes.

When +z (connected securely) isn't set on the service bot, and a services bot joins a +z (only secure clients can join) channel which only contains secure clients, then Unreal will send a NOTICE to the channel indicating the channel is no longer "secure" and unset +Z (which indicates that only secure clients are in the channel)

When +H (oper status hidden in /who, /whois & /lusers) isn't set on the service bot, the number of operators in /lusers appears higher than the number of "real" operators, as unreal doesn't exclude +S (services user) users from the list of operators.

what does +H mean? what does the mode signify?

[alicetries]

Ah, that'll teach me to not proof-read my comment.

+H causes the services bots to not be counted as 'operators' for the purposes of /who, /whois, /lusers and similar.
Unreal (unlike charybdis/solanum) doesn't exempt services users from those commands, which can cause some confusion with people wondering why their network has 16 operators on it (according to /lusers), where they only actually have a few real human operators & would prefer it to only show the "real" operators.

I appreciate it's more of an aesthetic issue, but there's been a few people mention this in #unreal-support over the past few months and finding it somewhat confusing.

[jesopo]

oh no im happy with this pr even for just aesthetics. just wondered if H had another meaning than just "hide from oper counts" to know if we'd be opting ourselves into other things by doing it. if not then

[alicetries]

Hmm. Unreal's source & wiki suggest "HideOper" / "Hide IRCop", and appears to just deal with the visibility of oper status in /who and such & maintaining the oper count for /lusers within source.

Think the closest equivalent is oper:hidden in charybdis/solanum, if that helps.
