Added --animation-duration-scale to allow the setting of a duration scale factor for all
animations using and derived from LinearAnimation.

This allows for easier testing and tuning of the many animations throughout the code. By
setting a scale factor, animations can be sped up or slowed down. This allows for them
to be better observed to ensure the intermediate states for transitions, movements, and
fades look good.
