Export - Re-worked the Title Listing JSON

The JSON for the title listing needed a few modifications.
I also change the way I was getting the title ids and namespace as the TtitleInstance.getIdentifierValue(ns) method is deprecated and should not be used.
Export - Add json export for Licences and Subscriptions

I've also re-worked the titlesList json.
Merge branch 'edina' into exports
Export - Open json format in a new tab
Exports - Add json export in Licence details, subscription details, package details pages

.. and a few fixes in MyInstitutionsController.groovy
Exports - removed unecessary CSV links

Some pages had a csv link (DetailsLicenses, DetailsPackages, currentLicenses and current Subscription) whereas the script for this format wasn't yet implemented.
Exports - XML format for Title List
Exports - Add XML format for Licence Details
Exports - add XML output for Package Details
Exports - Add XML output for Subscription Details
