Add static function to get a presenter for a corresponding view

Hi Adam,
awesome project!

I needed the possibility to get the corresponding view for a presenter. Therefore I created a static function on the view to find the corresponding presenter.

I added multiple error handlers and jacoco shows that I have 100% branch coverage and 81% instruction coverage. I am currently too lazy to mock InstantiationException and IllegalAccessException for Class.forName

Cheers
