Create prefix and suffix attribute for {{tags}} helper

[JohnONolan]

Tags need a concept of prefix so that they can work in themes even if no tag is assigned to a post.

Eg:

---

To my mind this should look like {{tags prefix="in "}} - and if no tags are present, of course nothing is output at all. So in the context of the screenshot above, you would just see the date.

This is an enhancement. For now you have {{#if tags}}in {{tags}}{{/if}}

👍

Also, it's a very nice enhancement but I think low priority given it can be achieved else-how.

That's fair - didn't realise it could be done the other way. Punted to 0.4

Following on from the discussion in ^

Spoken to a few people about this, I think the helper makes sense. I think we should also add a concept of "suffix"

Sensible, @cobbspur please can you tackle this?
