Reworked inventory rendering yet again. The interpolators are updated first, with animations set to begin at UINT64_MAX. Then, the items are renderered and animations with the bogus start time are reset to a common timestamp. Also added a delay before an item fades in that is proportional to the shortest position animation that is currently ongoing.
