Allowing the use of both objects and arrays for the register()

Sometimes we may like to use objects for lazy loading and whatsoever and since PHP has the Traversable interface, that should be perfectly fine.

Change closures to use $app as the first parameter.

Almost always the first parameter is $app therefor it makes little sense
to use `use` part of the closure and having PHP do context switching all
over the place.

This also makes it explicit in the service providers exactly what $app
instance is used.

feature #1175 Added factory for RouteCollection, makes subclassing of RouteCollection possible. (lschricke)

Added factory for RouteCollection, makes subclassing of RouteCollection possible.

Note: replaces #1174, which was targeting a wrong branch (and where I messed a bit with the commits ;)).

--

The aim of this PR is to allow developpers to subclass `Symfony\Component\Routing\RouteCollection` to change some of its behavior.

In most of my Silex apps, I figured I don't want the Symfony's `RouteCollection` regular behavior where if you define two routes with the same name (bad copy-paste for instance), the first route added simply gets overriden by the second. Instead, I would like to be able to throw an Exception if that happens. So I've written [a tiny subclass of RouteCollection](https://github.com/lschricke/symfony-strict-route-collection), but to be able to use it (through [a service provider like this](https://github.com/lschricke/silex-strict-route-collection-service-provider) for instance (needs to be updated for Silex 2)), I need to be able to replace `RouteCollection` by my subclass. This PR makes it possible.

Thanks! :)
