Do some console ops for visual tracking in authentication routine

* Also trying out *chalk* dep to see if the VPS pro logs can handle this without too much visual interference... nicer in development and debug modes... if not will remove.

Applies to Code Migrations, #430,  and jaredhanson/passport#400 (comment)

Still getting `username is taken` with *passport*@0.3.2 and *passport-github*@1.0.0
but **not** *passport*@0.2.2 with *passport-github*@0.1.5
