For Windows users, IrfanView (freeware) allows batch rotation and cropping (to specific sizes; it doesn't do edge detection, though I will raise a feature request). It's also useful for manual cropping, resizing, format conversion, etc. being small and lightweight.
I'm informed that IrfanView "auto-crop borders already works, with higher color tolerancy in: properties->editing" (I've not tried it, yet)
