pls add ironwail's hudstyle 3 support

[j4reporting]

Ironwail now does support hud first introduced in vanilla quakeworld clients. It would be great if copper could support this hudstyle in an upcoming version.

Even with latest compiled csprogs.dat, Ironwail's bonus HUDs ("Modern 1", "Modern 2", "Quakeworld") won't work properly. Either the keys aren't shown or graphics are overlapping. Also the "Mini" and "Full" modes are not really taken into account, as it seems. Often switching between settings won't make any visual difference at all.
