If newProjectURI is not empty, then a prompt is displayed on startup when no files are on the command line or when one chooses File->New from the menu. Kino promps the user for a project name/ID which is inserted into the URI where there exists a "%s" Then, the URI is requested from a server using HTTP. Kino expects to receive a well-formed XML document in the body of the response, which is parsed by libxml2.
