[MGPG-113] SignAndDeployFileMojo results in 401 (#82)

The RemoteRepository was "bare", it has to be equipped with AuthenticationSelector to be able to perform authenticated deploys. Also, remove "layout" as since Maven 3.0 there is no other layout than "default".

Also, a bit of tidy up, layout is deprecated in Maven3 and is unused.
