Integrations 2.0: JIRA Default map Aha! URL to JIRA Aha! Reference field

1.0 did this; 2.0 does not.

As a user I have to manually add the mapping between the URL field for an Aha! record and the Aha! Reference field for the JIRA record. 

For Releases we automatically map the URL to the description field.

For Features/Requirements we should automatically map to the Aha! Reference field if it exists.
