Title: Meta data layout

Apologies for the large commit history and change set, this is actually a merge of @indeox and I's work, that *had* to go out together for various reasons.

### What this does:
- Clean up Article, Gallery and Video templates
- Move dateline below headline
- Move dateline to left hand column at wider breakpoints
- Remove comment tab functionality (and thus a lot of JS complexity)
- Move comment count CTA to left hand column at wider breakpoints.
- Fix disscussion integration tests
