Bug#954658: Updated Patch

[Aaron Wyatt <dev@psi-borg.org>]

Also realised that hitting the cancel button on the settings form 
doesn't restore the previous settings within the UI. Have updated the 
patch to fix that too.

Make sure the frames setting is saved when it's the only setting that's changed.
Restore the previous settings in the setup form when the cancel button is pressed.
