Issue with ISession.getInput/setInput from Blitz

[jmoore]

Possibly related to #894, on a simple :

  setInput(sess, "a", new RString("a"));
  getInput(sess, "a");

the following is thrown:

Ice.UnknownException
    unknown = "java.lang.ClassCastException: java.lang.String

r2714, r2716, r2720, r2722 close. Used code from OmeroThrottling branch to add explicit casts in the return value casting in IceMapper. Slowly, all code will be moved to using the explicit casts.
