Devices with large amounts of flash but operating in connectivity-
constrained areas can benefit from using uncompressed images as this
allows delta updates using binary diff algorithms.
Connectivity-constrained areas in this context are defined as areas
where the connection is very slow, unstable, etcetera, where it is
difficult to transfer data in large scale.
Add a "none" option to the compression menu and map it to the mksquashfs
-no-compression flag to enable this feature.
Disable the ability to select extreme compression in this case as that
makes absolutely no sense combined with no compression.
