Basic bug fixes that alter the mod balance as little as possible file - Overthinked DooM^3 (Realistic Mod) for Doom III

The balance tweaks are:

Soul Cube damage is increased from 1000 to 1200 which is Hell Knight's health;

Sarge-Sabaoth is buffed from 4000 to 4200 hp, to compensate for the greater Cube damage that can only be dealt once;

Cyberdemon is hardened from 4000 to 4800 hp, just for it not to be less tough than Sarge in terms of hp, still taking 4 Soul Cube hits to kill.

'Shelob' Vagary is left as-is, 1600 hp, as the player first fights one without the Cube, and when facing two near the end of the game with the BFG and other heavy weapons the slight increase of the Cube's damage doesn't matter.

Impossibility to reload Super Shotgun when there is 1 shell loaded in it and 1 shell available has been fixed.

Lowering in case of wall/enemy proximity is now always disabled for the shotgun.
