Correct animation speed on some of the effects

[danwood]

In trying to track down why some animation speeds are incorrect, I found several easy fixes, where the animation speed was doubled for some reason. This fixes those ones.

(Still need to figure out how to make the 'fold' one more accurate (it needs to be scaled according to the number of slices, I think) and the various box effects -- Probably need to calculate something about how many total boxes there will be animated and thus how long they will take to animate, and then adjust the actual timings based on that and the desired total animation speed.)

This modification doesn't include the packed javascript file - I couldn't tell what tool you were using to pack your javascript.

@danwood can you expand on what it is you're trying to fix with this? I'm not able to see any speed changes between animations.
