Added a type for downloading an artifact from the nexus server
open-room-map: switched over one of the stages to use the new dtg::nexus::fetch type to download from the server
updated to fix broken URL and to move parameters to default arguments
openroommap:Updated to make use of default arguments on nexus::fetch
I had attached the default onto the wrong parameter - doh
open-room-map: added an optional unzip action to the nexus::fetch and added another use of it to the openroommap node config
puppet seems to be having trouble 'ensuring' the wget task whose action name I dervied from the path and name of the downloaded file - perhaps it doesn't like the '/' characters in it so I've reduced it to a filename only
Added a guard around the unzip package def to stop it conflicting with multiple uses
open-room-map: added another use of the authfetch
