remove data shipping with application builds

[okworx]

Now that we have the profiles as a facility to store a URL for the reference data, it is in principle no longer necessary to ship any data with the application.

At some point we might want to remove the default data, and only ship the default profile with the application instead. Users can then decide to either get the reference data from the location in the default profile, or their own.

This would avoid having to update the data shipping with the editor and actually make the user experience more consistent, as in any case updated reference data needs to be retrieved from the server.
