[WFK2-573] - Fix the time conversion for birthdates in contacts-mobile-basic.

Remove the earlier attempt with JavaScript and Java to fix this bug.

Converte birthdate to Temporal Date type.

The deployment relies on jackson-core-asl and jackson-mapper-asl modules in JBoss EAP 6.

The Jackson ObjectMapper is configured to ensure that Dates are serialized in the form of ISO 8601 full-dates.

Update the name of the JavaScript module from APPMODULE to CONTACTS_MODULE.
JDF-694 Fixed the parsing of invalid Dates at client-side.

Invalid dates input by a user, but having a valid date format are
validated using this fix. A temporary Date instance is created and
it's components verified against the user input.

This fix does not correct the behavior of the server to convert
the provided Date into a valid one.
JDF-703 Improved the REST semantics for the backend.

Contacts are now updates via PUT /contacts/{id}.
They're deleted via a DELETE /contacts/{id}.

HTTP 404 responses are sent when {id} does not correspond to an
existing one.

HTTP 409 is sent if the contact's Id is updated in a PUT.
Update the name of the JavaScript module from APPMODULE to CONTACTS.
[JDF-702] - Update contacts-mobile-basic to use jQuery Mobile 1.4.2 and JQuery 2.0.3.

Add the ability to dynamically change themes.
[JDF-702] - Attempt to fix the functional tests in contacts-mobile-basic. They are still broken.
[JDF-702] - Remove unneeded Themes. Fix footer styling to be display=block in contacts-mobile-basic.
