Rewriting - Storage no longer syncs metadata, only deals with file field and uploading.  using at_post_create_script and at_post_edit_script instead of events in content.KalturaVideo.  Leverage new 'syncMetadata' for edits, and 'createRemote' for creation methods.  Method '_createKobj()' will represent plone object as a KalturaMediaEntry.  If one field changes, the entire KalturaMediaEntry (all fields) are sent for client.media.update.  Death to '_updateRemote' which was a bad idea.  Moving more functions out of 'utilities' into archetypes class.
