New functionality - Straighten horizon

[JasonDS]

Hi, just putting forward the idea of a extension to the rotate function. Many pictures are taken of land and sea scapes. I would like the facitity to simply click two points on a photo and the software automatically rotate the picture to a horizontal line. Also, a check box called something like 'auto crop white space' would remove the white bits created by the rotate so that it is automatically tidy.

Regards,

Jason.
