Ban notice and banlist hidden for non-op users

[Mwyann]

Patch For Unreal3.2.7

What is it :
------------

Adds the +H channel mode that, when enabled, hides +b, +e and +I to "normal users" (voice or less). Opers can always see them.
It also hides ban list, exempt list and invite list (returns empty list).

Tested thru links, it works fine. +H adn bans are still applied over all links, modes are still passed to servers and hidden only
on local clients.

Why :
------

I made this so that flooders/hackers won't know how to walk around bans.

What's left to do :
-------------------

Check where ULines should have access always gained.

So, please propose your ideas about this new mode. Warning, this is not a module, but a patch : it patches some of Unreal core source files (sorry, there wasn't any other way to do this). It modifies src/send.c and src/moduesl/m_mode.c.

What do you think, about including this as a new feature in 3.2.8, or any other version of UnrealIRCD ? The bugtracker link hasn't been touched since posted...
