"Next" should be dislabed if the last file is reached

Up for discussion.

In my view, "Prev" and "Next" imply some order. A list. If the end of the list is reached, I would expect that there is no "Next". Thus, the button should be disabled. - Similar on GitHub with endless scrolling. At the real end of the changes, there is no wrap around to the beginning.

It would be nice to show the number of upcoming files in braces - or as tooltip "10 file(s) left"

Prev and Next buttons are disabled, and also show how many diffs remain to be inspected. Thanks @pouryafard75
