[sane-devel] more patches for epjitsu

[m. allan noah]

The big difference in speed when starting scanimage is probably the
number of backends which are active in dll.conf. Comment out the ones
you don't need. The missing S1300i might be a config issue also- is
the scanner listed in the epjitsu.conf file?
