This replaces grid hub usage in the material editor. It allows material editor and other tools to intercommunicate on the local host. This will allow enforcing that there is only one instance of the material editor running. Opening a second instance will forward command line options to the first instance running a local server. https://jira.agscollab.com/browse/ATOM-15439 https://jira.agscollab.com/browse/ATOM-13742
