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! :)

cascade route configuration for embedded route collection

In 4e6031e2, I added a safeguard by mistake which makes configuration on nested collection not possible. This fixes this issue but only for the upcoming 2.0 branch as it might break BC.

fixes #1017, #1100, and #1081
