[Translation] Add a way to retrieve the message catalogue from the translator

[schmittjoh]

Currently, there are no getters for the message catalogues of the translator.

This would be useful for tools that need to access that information.

The TranslatorInterface does not need to know how translation works. Furthermore, catalogues are lazy-loaded. So, there is in fact no way to get all catalogues. What we could do is add a getter for the resources, which are used to create the catalogues. Would that be useful?

[schmittjoh]

What I need is the raw translation message (with placeholders):

any news about it ?

[schmittjoh]

I'm using reflection for now, but still think that this would be useful.

I also need the raw messages, right now using reflection to get the catalogues. But it's not really nice...

@fabpot the getter must not be added to the TranslatorInterface. It would be enough if they are added to the framework's translator service. Or another interface, something like TranslationBagInterface, could be added.

And if the getter takes a (optional) parameter for the locale (e.g. getCatalogue($locale)) it would be easy to lazy load it with loadCatalogue().
