[sane-devel] permanent calibration files

I stored the location in the .conf file, so you can either set it as
implicitly per-user (with ~/.sane/blah, the default) or machine-wide.
Then you have to also account for read-only-ness, in case the sysadmin
would like to calibrate once and then not allow it to be changed (for
some strange reason).  Since you're working on the USB version of the
"same" scanner I guess we could have it somewhat consistant - but feel
free to do it a different way - I'm open to suggestions.

Cheers,
