[suggestion] Undo and Redo options for Scenario Editor

Getting something changed in a scenario, then be able to undo it, and redo said change would be extremely useful.

Though I would love these features implemented in this game, I recommend the other games to have them as well.


AoE3 has a undo and redo (and I think AoM too) but yes that would be nice to have.
AoE1 should get the AoE2 editor features. Not having triggers is a pain.
