Add ability to override NPC Jump Variables

[Bronzehawk75]

Adds 3 new key values and 3 new inputs to the base NPC class that allow mappers to change the jump variables on a per-NPC basis.

The jump variables are:

1. maxUp -> maximum distance an NPC can jump up. 80 by default. Changed with key value JumpUpOverride and input SetMaxJumpUp.
2. maxDown -> maximum distance an NPC can jump down. 192 by default. Changed with key value JumpDownOverride and input SetMaxJumpDown.
3. maxDist -> maximum distance total an NPC can jump. 250 by default. Changed with key value JumpDistOverride and input SetMaxJumpDist.

This is what I was always looking for
btw how's the result when you test it with NPCs that have different Jump Variables, like Fast Zombie and Antlion?
