Maintenance release for initialScreen/homeScreen query parameters

[jonathanolson]

It would be good to have this added to sims retroactively where needed.

See phetsims/qa#642 (comment) for sims

Patched the "broken" homescreen cases with patches for #641

[jonathanolson]

Looks like explicit decisions were made to error out and not launch simulations when one screen was visible:

      // Problems related to query parameters throw errors instead of assertions (so they are not stripped out)
      if ( QueryStringMachine.containsKey( 'homeScreen' ) ) {
        throw new Error( 'homeScreen query parameter not supported for single-screen sims' );
      }
      if ( QueryStringMachine.containsKey( 'initialScreen' ) ) {
        throw new Error( 'initialScreen query parameter not supported for single-screen sims' );
      }
      if ( QueryStringMachine.containsKey( 'screens' ) ) {
        throw new Error( 'screens query parameter not supported for single-screen sims' );
      }

We don't do that in master... should I remove the explicit errors?

Closing, handled in maintenance release deployment.
