The current --with-javafx configuration script expects the structure of a standalone JavaFX SDK where it is under rt/lib/jfxrt.jar.  Can the configuration script be changed to accommodate both situations?

I think the case where we're using the JavaFX bundled with JDK or JRE
should be handled by *not* setting the classpath.

I.e., when using configure,
--with-javafx (wth no path) should mean to enable JavaFX, but  without 
changing
   the claspath
--with-javafx=PATH/jfxrt.jar should mean enable JavaFX, and set
   $conf_classpath to include the specified jar.

For backward compatibility, the previous form should check whether
PATH/jfxrt.jar or PATH/rt/lib/jfxrt.jar exist.  I.e. if the former
doesn't exist, but the latter does, use the latter interpretation.

At some point we might want to make --with-javafx the default - though
perhaps not unless building for Java 8.

Ant builds should do something similar, but could perhaps default
to enabling javafx if a suitable marker class (say javafx.scene.Node)
exists.
