Try mode

[nelsonic]

Adds regression test for try and optional auth modes.
see: #111
Without the lines:

if (!token && request.auth.mode !== 'required') {       
   return reply.continue({ credentials: {} });      
}

it actually works exactly as expected.
Confirmed by the master in: hapijs/hapi#2843

@alanshaw I took the regression tests directly from your branch: alanshaw@736067f
please checkout this branch and confirm it works as expected.
Thanks. 👍

LGTM - the tests in my application pass with 5.1.0, fail with 5.1.1 and pass again using this branch.
