I changed the theme to xcode but now after refreshin the page I again see the default monokai theme.

Whoops, sorry about that!

We do indeed overwrite any user settings in that's also our fault, we overwrite any existing user settings in https://github.com/JanitorTechnology/dockerfiles/blob/7a8d767062eb2c1a/ubuntu-dev/workspace-janitor.js#L63

I think we should be smarter than this, and find a way to overwrite the default Cloud9 config, but keep any user-specified changes unchanged.
