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.
