Added

• Support for variadic handlers in New()
• Added Negroni.Handlers() to fetch all of the handlers for a given chain
• Allowed size in Recovery handler was bumped to 8k
• Negroni.UseFunc to push another handler onto the chain

Changed

• Set the status before calling beforeFuncs so the information is available to them
• Set default status to 200 in the case that no handler writes status -- was previously 0
• Panic if nil handler is given to negroni.Use
