Split out code to get the debug socket so that we can call it multiple times if chromium is slow to startup. Will try after 200ms and then 2 times after 2 seconds.
Merge branch 'master' of https://github.com/sihorton/appjs-deskshell
New release of deskshell. Refactored so executable now runs deskshell.js and that handles the application that is passed or runs a default application.
