Version20

Adding Symfony bundle and some basic infrastructure.

This is where version0 should have been.

Few things to point out here. Firstly, the lightweight controllers. They
do little more than take the request, set up the command and pass it off
to the handler.

When I first started this, I had seen a few tech talks and was all about
decouple from the framework, controllers as services etc. I agree
massively with decouple from the framework with regards the domain and
even the ports layer (commands/handlers) but I've come a little bit full
circle in the controllers as services and using DI to completely
decouple your controllers. I know think, it doesn't really matter. So
long as your controllers are really light, it doesn't really matter if
they're coupled to shit, because essentially they don't matter. They are
merely passing messages from framework to domain. The second point to
note is that you can see from the images and twig templates how advaned
my UI is :).
