Tweak range steps in the animation editor

This makes the step of the "frame" SpinBox larger, so that clicking
on the SpinBox arrows will make the number increase in a visible manner.
Previously, the full number was being cut off due to the SpinBox
being narrow.

This also makes the "step" SpinBox allow for more precise input.
