[Koha] More on Z39.50

[Tonnesen Steve]

Thanks for the testing!  Your testing pointed out some small problems
which I have corrected. 

I wasn't removing the '-'s from ISBN's.  I am now.  You can put in the
dashes or leave 'em out.  They'll be removed before querying the Z39.50
servers.

I wasn't accessing the full AMICUS database at the National Library of
Canada, so whoever searched for "Global action for biodiversity: an
international framework for implementing the Convention on biological
diversity" will find that it finds it successfully now.

I've added a note saying how many records were found for each query in the
queue.


Now I really need to get full MARC support in Koha so that all of this
data doesn't have to get mangled.  :)

Steve.
