--User changes

-Always force times of each flame to increase from zero when saving a file.
 -Remove check for times when doing a sequence in EmberGenome because the original times are never used there.

--Bug fixes
 -Multi-GPU synchronization was not actually thread safe and was likely doing less iters than requested. It is now properly synchronized.

--Code changes
 -Optimize Interpolater by making it a non-static class by adding some members used for caching values during interpolation.
 -Cache values in SheepTools as well, which was already a non-static class.
 -General cleanup.
