Refactor download action in DefaultController

Added visibility filter to download action
Add XML data repository for development without SIS

The SIS data will be loaded from local XML files instead of making SIS
connection. As SIS API requires firewall and auth2 service account to be
set up. This will enable local development without a real SIS
connection.

Also renamed SISAPI to LtCommons
