Slightly fixed rotation issue.

It turns out the the bitmap width and height were always returned such
that the image appeared to be in landscape mode. Thus, my autocorrection
failed. I instead added two button on the Note Viewer page so the user
can rotate the image so it can appear correctly. I know have to add a
button to upload the corrected image.
Added reupload button in Note Viewer.

The user can now correct a rotated note and update it so that it is
reflected in the server.
