Obstructed Buildings in Blueprints Should Flash When Placed

[infogulch]

When a blueprint fails to be placed it can be difficult to determine exactly what is in the way and where the obstruction is within the blueprint. (This can be especially true for large blueprints and small obstructions.)

I propose obstructions and obstructed buildings in the blueprint should flash noticeably when a blueprint fails to be placed.

Right now, as you're dragging the blueprint around, obstructed buildings in the blueprint are highlighted red. If the user tries to place the blueprint anyway it means they did not notice this cue and should be notified of the obstruction more strongly.

(I first saw this idea by Ranakastrasz in the thread Force-place Incomplete Blueprints, and thought it deserved its' own topic.)
