Prepare Code for integration with code-server

1. We already have the arguments so allow passing them in.  There is also a
   slight change in a few directories to preserve the directory structure we
   have been using and to not override passed-in arguments.
2. Modify the terminal environment to filter out code-server environment variables.
3. Add the code-server version to the help dialog.
4. Add ready events for use in an iframe.
5. Add our icons.
6. Use our own manifest.
