[RFC] Added possibility to configure PresenterFactory mapping via array

[ghost]

BC break: no
Documentation: needed

Solves: #101

[ghost]

(Still in progress.)

I realize this must be written differentlly, Parts of array must be validated and this must be allowed:

$factory->setMapping([
    '*' => ['App\\', '*'],
]);
Assert::same('App\RedDwarf', $factory->formatPresenterClass('RedDwarf'));

Ok, there is a proof of concept solution (I moved from red to greeen). Plase give me some feedback if I didn't miss any case or if there any missing functionality.

Then I'll do some code cleaning & refactoring. I would like to extract the logic of parsing into some "PresenterMappingParser".

@achse can you please simplify this? is an array with 1 and 2 items really necessary? I think the version with 3 items is sufficient.

I am very busy right now. Please, anyone is free to fork my PR and finish it or write it from scratch. Just tell here, to prevent simultanous work. I dont know when I get time to finish this.
