A new, modern HUD layout for the Nugget Doom source port.
- re-arranged Doom's stock HUD elements
- restored HEALTH/ARMOR/AMMO stbar labels
- support both 4:3 and Widescreen aspect ratios
- tweaked palette for STGNUMx and STYSNUMx lumps
- crispy hud look & feel, even when using PWAD (thanks to NUGHUD's font override feature)
