-Fixes to undo redo to avoid crash, closes #24251 · 4a24ba6eJuan Linietsky authored
-Changed Animation to have a special signal when tracks are changed, to avoid unnecesary track cache rebuilds in AnimationPlayer -Added missing emit_changed whe modifying keys to Animation -Changed AnimationPlayer to use the new refcounted connections instead of the previous hacky way to keep references -Changed AnimationEditor to update the current track when keys are edited -Fixed bug where undo/redo did not work with AnimationKeyEdit (was not being updated) -Made sure UndoRedo does not mind deleted objects in undo/redo history, this would corrupt the history or clear it without need.
