Don't sign the webstart jars by default.

We're going to be code-signing in a separate process, so this prevents jars being double-signed, once with the self-signed cert and once with a proper one.

The webstart-sign target is still there, so you can use `./build.py webstart-sign release-webstart`.
Add an external webstart signing script

Automatically run this script with the existing self-signed certificate as part of the standard docs/hudson/OMERO.sh build
