hotfix: adding back spawn distance settings

Major Content Update (Difficulty System) - Version 1.0.1.0

Highlight:

- Added Difficulty System: Normal, Hard, Realism. As the difficulty increases, expect enemies to scale in health, damage, numbers and intensity, while players receive additional penalty in economy. See a more detailed description here: https://github.com/tpan496/Horde/wiki/Difficulty-System

- Added Endless Mode: You can now toggle the game to be endless. In endless mode, enemies will scale in health, damage and numbers as the wave increases beyond infinity.

- Added Random Ammobox Spawns: Ammoboxes will now spawn randomly across the map. They will refill all your weapons by 1 weapon clip. The number of ammoboxes spawned will be related to player counts and difficulty.
