JAL-3065 - amended commit 4906697ab6e5a79fbce3baae89f7f64178c9a739 to exclude .settings/..groovy Added notes to the instructions, also adjusted the jalviewDesktopRunner test to lookup OS and use ';' or ':' accordingly. All the CommandLineOperations tests failed on my (hastily set up) linux box, so I'm committing and will test on MacOS too.
