Implementation of the new World Nomads insurance quote widget.

## Narrative
World Nomads has a new version of their booking widget that we need to implement. With their previous version, we built our own widget form from scratch to mimic theirs and simply pulled in a script from their domain to manage its functionality and validation. With this version, we're pulling their unstyled widget in wholesale, and simply applying some Lonely Planet styles on it.

## Verification tasks
1. Verify that user can enter in multiple destination countries and that each is turned into a badge above the input field.
1. Enter Australia as the country of residence and verify that the form asks for a list of ages for who is travelling.
1. Enter USA as the country of residence and verify that the age field converts to a radio button group where you can select single, couple, or family.
1. Verify that submitting the form takes you to the World Nomad quote page.
1. Verify that the form will not submit if (a) the destination is not set, (b) the country of residence it not set, (c) if the country of residence is set and the age field is displayed but there is no value in it.
