updating documentation to use new glosary

As a follow up of https://github.com/openmicroscopy/openmicroscopy/pull/3020#issuecomment-55398118 there is an update of the OMERO.web doc
@aleksandra-tarkowska Was there another commit for this? I don't see it working at https://www.openmicroscopy.org/site/support/omero5.1-staging/developers/Web/CreateApp.html
