Allow users to select Menu style

[MrWabbit]

People might want to retain the classic HUD and use a transparent menu style like greytones.

facilitating this is relatively painless.

In CortUI settings make a variable called MenuStyle?
values:
NormalHUDMode | 0 | 1 | 2 | 3 | n
where n is the number of possible future HUD mods.

in the install form use a drop down box with the values:
use recommended | classic | GreyTones? | GreyTones? | GlassHUD

in the MDLs I would use MenuStyle? as the Switch variable. With default settings, MenuStyle? = NormalHUDMode. Otherwise, user supplies the style number of his choice, which correspond with Hud numbers.
