Dev/70/carles show details

This is not intended to be merged, but mainly for discussion.

When trying to glue things together in a quick first initial story detail view, I realised the JSON data structure we are generating right now (nested dictionaries) is not ideally suited for iterating in Javascript and Angular-JS templates. See my inline comments in the PR. 

We may want to come with a properly defined feature data structure (and in particular all attachment info: repos, branches, build results...) before getting much further.
