* 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.
