Larger threshold before cloning/movement/rotation

[Frank]

I don't recall having this problem in earlier versions, but the things I've been building recently are much more complicated, so perhaps I didn't discover it until now. Very often, when I'm using CTRL to select large numbers of objects and groups, I will find several steps later that I accidentally cloned what I was selecting at least once while I was going around selecting all the objects I wanted to do something with. This is apparently the result of me sliding the mouse a pixel or so while I click an object I want selected. Less often, I will find that I accidentally moved something, or I rotated it while right-clicking to open the object's menu.

Identifying, going back, and fixing mistakes like that accounted for a good ten or fifteen minutes of a recent two-hour build session, and all of it could be avoided by reducing the sensitivity of these functions so that they don't activate until the mouse has moved a couple of pixels.
