Soft drop fix was never looked at again after it was removed

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Soft drop in a mode like Grade Mania
2. Notice that soft drop is additive (i.e. current gravity + 1G as opposed to 
just 1G)

What is the expected output? What do you see instead?
In order to properly emulate all possible rules/games, there needs to be three 
kinds of soft drop as opposed to just two: normal, additive, and 
multiplicative. "Normal" should always set the soft drop speed to the given 
speed, without regard for the current gravity speeds, and it should be 
ineffective (besides locking, if that is enabled) when the gravity speed 
exceeds soft drop. "Additive" acts as normal soft drop does now, by adding the 
soft drop speed to the current gravity settings. "Multiplicative" already is a 
setting, where the "soft drop speed" is actually a multiplier of the current 
gravity speed.
