Subject: [PATCH] Accept Dugdale Arts Centre's explicit empty film listing

The venue currently has no films scheduled and its listing shows an
explicit empty state, which the transform treated as a broken parse.
Follow the Curzon Sea Containers pattern: no movies is only accepted
when that marker is present.
