Import reference image & Image plane in a perfect Axis

This, I think, it's a minor adjustment but that It would be nice to have. Every time I import an image from perspective mode, it comes with a weird roration. So I press alt + r to put it flat, and then I rotate accordingly. I think it's better that by default all images imported (from perspective mode) are rotated perfectly along an axis. Basically you just omit the alt+r command.

And then you can rotate however you want.

What do you think?
