Change file dependency for Electron, so unused *.node binary files for nw.js can be removed from Electron build app directory without causing a C3 error. In the efc Electron build the *.node files are included separately and are updated for the version of Electron being built. Currently, when the application is run, a console warning error occurs due to the file names also being included in app/offline.json. To eliminate this warning, edit app/offline.json before building with efc. Remove the following strings from the offline.json string array: "greenworks-win32.node","greenworks-win64.node","greenworks-linux32.node","greenworks-linux64.node","greenworks-osx64.node","greenworks.js".
