Remove useless / problematic entries in setup

[atsb]

EX+ should be simple and easy to configure with no settings that can drastically break or interfere with a wad's intended look and feel. Some settings break the visual / gameplay dynamic the author's intended.

All settings except:
Jumping
Mouse Aiming
Monster Height

Will be removed.

• This also includes the N64 compatibility settings, which will be restored to exactly how they were in vanilla.
• Lost souls will be limited to prevent possible crashing on lower-spec systems with unlimited lost souls.
• Setup will be renamed Configuration

For the purpose of a stable and reproducible configuration for PWAD author's, this is vitally important. Giving the user so many options to break the experience just causes issues for those author's.

This is not up for discussion.
