closes #942 - insert custom middleware to check for blacklisted files - redirect to express.static if file accepted - if not valid return next() to do nothing - currently black listing .hbs, .txt, .md and .json - debatable which is best, black list or white list, either one will probably need tweaks but erred on side of letting a theme serve unknown types
