[Feature request] Add image rotation function

[rado84-github]

Is it possible to add a function somewhere (probably under "Transform" tab) to rotate the image by 90 degrees in each direction for totally 360 degrees?
I've got some images I need to rotate and now I gotta download a separate app. I'd very much prefer to use Simple Gallery for that than having to download yet another app.
