In the previous versions, the sink (where the entries should be written to) was not passed. This did conflict with the libimagrt holding the stdout/stderr handles, because it automatically writes to stdout (which we don't want to do in some cases). Passing the sink is way nicer. This patch changes libimagentryview so that the sink is passed to the viewer.
