qol Cancel Build Action - bring back up previously active plan and overlay ( when).

[The Plum Gate]

Having to cancel a build order in the middle of building or layout of a large and complicate plan often results in having to cancel all of a particular plan's sub type, or specific things while in a build mode. There is also the issue of inadvertently placed pipes, flipped bridges, and so on.

The cancel order should remember the the previously active overlay and plan category and possibly the last active item selected to be built. and then automatically make all those things active again after canceling if the last reasonable action involving UI interaction involved building within the plan category from which you canceled.

Basically if the cancel action is associated with the last active build overlay, and the canceled builds were part of that last active overlay by type designation, then bring back up the overlay, and bring back up the last active plan category. Further, if the canceled build order was the last active build - bring back up the overlay, the plan category, and the building type.

The request comes out of misplacing bridges mostly, but it really evolved from the inability to click on a bridge while in viewing mode to cancel it manually - and because the hotkey for cancel is easier to hit than button on the screen. Cancel also drops the active build menu, and occasionally the overlay - you have to hit even more buttons...in that case.
