A few bug fixes

FIXED: regeneration of access token was failing because the API call made was incorrect
FIXED: since namespace was given OauthException class was unable to find \Exception
FIXED: user was unable to continue session after a few hours
FIXED: code bug wher undefined $redirect variable was being used.
