Brutal Doom V20b Menu & HUD Patch addon

The patch simply fixes the folowing:
----------------------------------------------------
-The status bar has been adjusted to correct the ammo capacity for bullets. It works on both classic and modern classes, 300 bullets max without the backpack, 600 bullets max with the backpack.
-The Brutal Doom Options should be found on the main menu in order to work with GZDoom 3.X.X and Zandronum 3.0. It has been tested on the source ports mentioned as well as QZDoom and ZDoom.

Credit goes to Sgt_MarkIV and creators for Brutal Doom, I only made a patch to fix some errors to keep up to date with modern engines.
