Bug 10558 - Convert records table in manage-marc-import.pl to Ajax DataTable

Bug 10558 - Convert records table in manage-marc-import.pl to Ajax DataTable

Some libraries would like to sort by columns for the records of an
import batch. This seems like a good use of Ajax DataTables.

Test plan:
1) Apply this patch
2) Import a record batch into Koha
   a) Use some form of matching
   b) Have some records that will match and some that won't
   c) Have at least 30 records so you can test the pager
3) Verify the new table is functionally equivalent to the old static one

Tests fine and looks good with the exception of the corrections I put in
a follow-up.
