- flattened the following commits by Major Cooke:

Browse source 
* Added falloff parameter to A_QuakeEx.
- Treated just like A_Explode's 'fullradiusdamage' parameter, where the quake will fall off from this distance on out to the edge. Default is 0, which means no falloff.
- Credits to MaxED and Michaelis for helping.

* - Added HighPoint parameter to QuakeEx.
- Allows fine tuning of where the quake's maximum or minimum occurs, in tics. This must be a range between [1, duration).
- For up or down scaling quakes, this sets the quake to reach maximum sooner or start minimizing later.
- For both, this indicates when the strongest will occur. Default is 0, or in the middle.

The original commits were nearly impossible to find in the convoluted commit tree, so I think it's preferable to have one clean commit instead.
