LP#1731021: Support fine detail enhancement to SIP.

The particular flavor of fine detail output is manufacturer dependent,
although 3m is popular, and the default.  To configure the selection,
modify the /openils/conf/oils_sip.xml file.

Testing: See the /openils/conf/oils_sip.xml file and test all supported
values for the av_format option.  You should also test the case where
the option is omitted, or a non-supported value.  I am not sure what
happens if you supply more than one option with same or different
values, but this is a non-supported degenerate case.

For each test value, ensure tha the fine item detail is the expected
format.
