Remove ManagedRawFileStoreI in favor of callbacks

ManagedRawFileStoreI was not being used which meant that
closeCalled was never invoked and therefore the proxies
in `ManagedImportProcessI.uploaders` were never cleaned.
This led to `ObjectNotExistException` being thrown on a
second loading of `proc.getUploader(i)`. Rather than add
logic to create the correct subclass of RepoRawFileStoreI,
a callback interface has been added which can be used for
any implementation.

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.

Reduce memoizer wait to 0 (Fix #10337)

For relatively fast setId alls, no bfmemo file
was being produced. Lowering this value to zero
shaved off 1/3 of the setId time, though, even
for fast files.

This should also prevent discrepancies when the
system is underload: now a memo file will always
be produced.
