Replace AngularJS For Content Page Rendering

Right now we are using AngularJS to drive our sites. This poses some problems which need to be addressed before launch (making the content available to search engines, multi-language deep link support). As the power of AngularJS is only necessary when using complex interactive elements (like the banner configurator) and no work has been done regarding to displaying content other than simple strings I am moving all non-interactive pages to server-side rendering via Symonfy2.

This also includes updates to enable the rendering of content other than simple text-strings.
