Escape key

[Zarat]

The escape key is kinda standard with most games these days so I was surprised to see it not working. It seems you kinda replaced the escape key with right click in most places, which for the average user is very unexpected. It would be nice if you could add escape key functionality. (I don't mind if you keep the right-click functionality of course!)

Escape key should
- Close currently active dialog/popup (cancel if there's a choice between accept & cancel).
- In the main game, if there's a tool currently selected, unselect it instead of opening the menu. If no tool selected you could still open the menu if you really want to.
