[Feature request] CP eraser brush

Removing control points with Ctrl+RMB drag may be great for architectural scenes, since there are many vertical lines, but for nature scenes it's not very handy. In this kind of situation, an eraser brush would be better.

I make a large number of 360 panoramas in nature and since they have to be made with high precision, I generate a large number of control points and remove those that are unreliable (branches that may move in the wind or close objects that may have parallax) and using the rectangle selection is without a doubt more time consuming than a brush would be.
