Request: Scenario editor updates

Could we get an update to the Scenario editor that brings back the grid unlock from HD? It is really cool to make scenarios with mixed buildings and such.

Could we also get the ability to display messages like in the new campaigns? Like with the picture of the person saying it, and being able to send a message longer than those short ones we can send now.

Also, a guide to the new scenario editor features would be fantastic. Maybe that and other written guides and articles could go in a new tab, as with the History tab.

Finally, thanks to the devs for putting the trigger conditions/effects lists in alphabetical order. It saves so much time!
