* Taseditor: fixed bug with history undo not setting "project changed" flag

* Taseditor: Greenzone invalidation actually clears irrelevant savestates
* Taseditor: fixed checkMarkersDiff, removed unused code from MARKERS_MANAGER::RestoreFromCopy
* Taseditor: when snapshots sizes differ, findFirstChange returns size instead of last frame
