Add more features for modifying the display of a document when batch scanning

It would be very useful to add more features to modify/display a document when doing batch scanning:

• Ability to rotate the entire document and not juste one page at a type

• Ability to drag pages to change the order of pages in cases where the pages weren't scanned properly

• Ability to delete multiple pages at once (right now we can either delete one page at a time or delete the entire document)
