- Added A_JumpIfHigherOrLower.

Browse source 
- (int ptr = AAPTR_TARGET, state high, state low, float offsethigh = 0, float offsetlow = 0, bool includeHeight = true)
- Jumps if the pointer of the calling actor is higher or lower than itself, adding offsethigh or offsetlow depending on the circumstance.
- includeHeight works twofold.
- Includes the height of the calling actor if the pointer is higher to truly determine if they are completely above them or not.
- Includes the height of the pointer if the pointer is lower.
- Disable it to only check z differences without adding height.

// A_JumpIfHigherOrLower
//
// Jumps if a target, master, or tracer is higher or lower than the calling
// actor. Can also specify how much higher/lower the actor needs to be than
// itself. Can also take into account the height of the actor in question,
// depending on which it's checking. This means adding height of the
// calling actor's self if the pointer is higher, or height of the pointer
// if its lower.
