Normalize ISBNs by stripping hyphens in search methods and in reporter.materialized_s...

We weren't normalizing ISBNs in search or in reporter.materialized_simple_record
which required users to exactly match the form of the ISBN as entered in the
MARC record to get a successful search result - pretty hit or miss.

The longer term fix in 2.0 and above is to make the ISBN search search against
the identifier|isbn index, which also gets ISBN10/ISBN13 equivalence goodness.
But this patch will be relatively easy to backport through to 1.6.1 and plugs
some of the holes in our exposed APIs and search points in the short term.
