Handling updates to the JavaFX Caspian look

[Richard Bair]

> Separate discussion, but this relates back to auto-updates and having control over when JFX upgrades itself. I'm still voting hard and loud for developers having some control over this, even if it's just something we have to manually configure (i.e. the default is to auto-update) and maybe can only do for non-applets - therefore be it on our own heads if any security holes hit us.  

We will solve the compatibility problem. Although Applets may have no guarantee (at least, applets in their current form), WebStart based applications will have some mechanism for preserving what version of Java/FX you run against.
