Allow javafx to be run.

The current version of openjfx has a requirement
that beans are defined with their types in
the format <bean-name>:<class-name>
Hopefully, this will change, in the meantime
this hack allows openjfx scripts to be run
in ant as follows:
  <script language="FX" manager="javax">
    <classpath>
      <fileset dir="${user.home}/apps/openjfx/trunk/lib"/>
    </classpath>
import javafx.ui.*;
		
     Frame {
            title: "hello"
            width: 200
            height: 50
            content: Label {
                text: "Hello World"
            }
            visible: true
     }
  </script>
