Bug 5608 - command-line tool to switch information in 440 and 490 tags

With the MARC21 standard moving from the 440 tag to the 490, this tool is
to help libraries make the move.  It switches any information in 440 tags to
490 tags, and any information in 490 tags to 440 tags.  That seemed like the
best way to go to me.  There is also an option to create 830 tags for any 44
information, like authorities, that can't be represented in the 490 tag.

To Test:
locate some biblios with 440 or 490 tags filled.
run bin/migration_tools/switch_marc21_series_info.pl -c
observe that the information in the biblios has switched 4xx tags.
