Fix inconsistent behavior of diff view when viewing binary files
In the new change screen, if the user clicks on a binary file in
the file list, the unified view is used. Then when navigating to
a previous or next file that is not binary, the diff view stays in
the old unified setting. It is only possible to get back to the
new side-by-side view by going back to the change screen and then
opening the non-binary file from there.
To keep consistent behavior of diff view, always use unified diff
for binary files. Use the user's preference setting for non-binary
files.
