Allow tags anywhere in titles

[kennygrant]

Adding a tag at the start of a title renders the entire title invisible, this was unintended. If users wish they should be able to add tags earlier in the text, or we should at least warn about this problem.

We do extract tags (unlike twitter), so this could be an issue for users expecting to see tags inline in the text.

Not sure how best to handle this as I'd prefer not to leave tags in titles as twitter does (looks a bit ugly). Perhaps just add a warning for users if tags detected with non-tags after.

Closing as would prefer to keep tags at the end and extract them there.
