Use 'get' instead of 'match' in config/routes
Use strong_parameters
Use \A and \z in regexes
fix use of valid_params in PostsController
fix Blogit::PostsController#update
Remove post-tagging
Always paginate post index

In addition to just being a good idea, (the data returned shouldn't depend on
the format it was requested in) this is was fixes an interaction with mobile-fu
when it would cause the response format to be "mobile" instead of "html".
