* Add the last known parent to the prefab undo cache to detect changes in the owning instance.
Still WIP.
* Progress in handling reparenting. Still WIP, need a change in CreateLink that will be addressed in a separate branch and then merged back.
* A few fixes, reparenting now works with entities. Still working on instances.
* Fix assert crashing the Editor because of the arguments being in the wrong order.
* Handle moving the patches when removing and recreating links when reparenting nested instances.
* Rearrange some code to prevent including instance removal in instance update undo node, as it would be redundant and cause errors in some edge cases.
* Reorder instance reparenting to account for correct order of operation during undo/redo
* Fix order of operations to support multiple operations in one edit (reparenting to non-container entities while changing instance)
* Add function to refresh patches on links to allow aliases to be restored correctly on reparenting.
* Removed RefreshEntityPatchOnLink function. Introduced a simpler way of handling porting patches.
* Removing unnecessary code that was left after testing.
* Minor fixes to naming and comments.
* Restore previous error, no longer printing the failed patch.
* Remove unused includes.
* Restore include removed by mistake.
* Simplified patches retrieval by using internal function. Renamed some internal functions and variables to be more accurate.
