Refactor postcode lookup js to use MOJ js standards
Avoid duplication of objects
Amend to only look in particular wrapper rather than whole form. Means multiple per form can be used. Ie work and home address separate lookups
Remove legacy plugin
Add dummy test data for postcode lookup so functionality can be tested
Merge pull request #132 from ministryofjustice/feature/pcode-lookup-js
