Update checksums for marriage-abroad
Update checksums for marriage-abroad

All regression tests are passing so I've updated the checksum data
accordingly.

Updated using:

    $ rails r script/generate-checksums-for-smart-answer.rb \
    marriage-abroad \
    lib/smart_answer/calculators/marriage_abroad_calculator.rb

Note the addition of the new calculator in the list of files we check
for changes.
