Title: Refactor list of roles that assets are compiled on

By moving the list of server-roles that the Rails assets are compiled on to a method, it's possible to override this method with your own set of roles. This for instance makes it possible to also compile assets on a util-server.

For details of how to override, see:

An simple use-case could be if you generate and e-mail PDF's using a background job. If these PDF's contain images or other assets that needs to be compiled into the PDF, these assets needs to be compiled and available on the utility server.
