Title: added option to generate card migration with json import

If the card migration name matches import\_(.\*)\_from\_(filename:.\*) then the
migration is set up to import json data from db/card_migrations/data/\.json

Improves also the migration syntax. `contentedly do ...` and `include Wagn::MigrationHelper` is no longer necessary.
