Bike Theft Flair

This was suggested recently, so I've put it in place. When you create a post, you'll have the option to 'Add flair and tags' - at the moment the only flair is 'Bike Theft', which has a red background to help it stand out, both for whoever wants to get involved in the discussion and also for anyone who wants to scroll past.

Let us know your suggestions for other flair. We might even implement some of them.
