Bug 18690: Use MARC modification templates with bulkmarcimport.pl

Bug 18690: Use MARC modification templates with bulkmarcimport.pl

When importing large numbers of MARC records from a legacy LMS to Koha
using bulkmarcimport.pl, it did not make use of the MARC modification
templates in the system (which can be useful for coversion of 852
fields to 952 fields for item holdings for example). This patch allows
MARC modification templates to be used with bulkmarcimport.pl.

To test:
1) Apply patch.
2) Set up a MARC modification template (in Home > Tools > MARC
modification templates) to make some changes to imported MARC
records (for example copy a subfield).
3) Take a test set of MARC records that have fields matching the
template and import them using the bulkmarcimport.pl tool. For example
if these MARC records are in testrecords.mrc and the MARC modification
template is called testtemplate use something like:

   perl misc/migration_tools/bulkmarcimport.pl -commit 1000 \\
     -file testrecords.mrc -marcmodtemplate testtemplate

4) Check the imported records in Koha to see that the required
modifications have been applied when the MARC records are imported.
5) Sign off.
