Add a reference to presenter within view

[GoogleCodeExporter]

Adding a reference to the presenter within the view makes it possible to use 
the @UiHandler annotation of UiBinder. This is relatively simple to automate 
in GWTP and shouldn't even be a breaking change.

See:

For details.

In my sample app I had a reference to the presenter from within the views 
without modifying 
gwtp.

- My View interface has a Presenter sub-interface (not sure for the technical 
term for 
this).  It defines methods that handle events, such as onSelect, onXXX and 
onYYY.
- My Presenter implements the View's Presenter sub-interface.
- My ViewImpl is constructor injected with a provider of the presenter 
sub-interface.
- My View's Presenter sub-interface is bound to my Presenter using bind().to();
- My ViewImpl has @UiHandler methods that handle events are then forward them 
on to the 
presenter using this.presenterProvider.get().onXXX()

gwtp could possibly automate the last 3 steps.

Brendan's approach is simple enough, and I've been doing something similar in 
my own application. Bottom line I believe it is best to leave that up to the 
user, so GWTP will not be enforcing passing the presenter into the view.

We could at least document this pattern in a how to section with a simple 
example.

I totally agree, I've added Issue 123 for this.
