Nearly working artifactory publish

The artifactory-publish resolver can now be used
from the `release-hudson` target to publish all
the OMERO jars to the OME artifactory repo. The
only parameter needed is a password for hudson.
Override 'artifactory' target in insight

Since insight does not produce all the artifacts
upfront, the target needs to be overwritten like
the `install` target and "haltonmissing" passed.
Omit Bio-Formats component

Since Bio-Formats jars/poms are pushed via
a separate job, the release-hudson target
will now skip that component.
Make repository name configurable

Now, by using `ant release-hudson -Dartifactory.repository=foo`
or setting the same in etc/local.properties a repository other
than ome.staging can be used. Most useful is setting it to
ome.unstable for merge builds or ome.snapshots for latest builds.
