RT-25559 Allow event handlers to come from the namespace

[Daniel Zwolenski]

I've always wanted the ability to have any bean in the scope and be able to arbitrarily reference properties and methods on it as needed, ideally using the $ syntax for everything. 

Eg

<Button text="$myModel.someValue" onAction="$myPresenter.doSomething">

Where I add myModel and myPresenter to the FXMLLoader scope via something like set("myModel", new MyModel()), etc. 

This would stop the hard "controller" concept and allow developers to use whatever pattern they like (eg bind directly to a model, etc). 

There's some issues on tool support for this (ie the tools don't know the type of myModel) but there are plenty of options around this - discussed previously but I can find them if there's any interest.
