Fix expire_time description to show correct default time of 1 day.
Fix cookie bug when Javascript was setting a cookie it was setting a cookie of 'now' instead of the set config of expire_time into the future when the cookie should expire.
Added the challenge cookie to the headers set by grant_access function to update the cookie set by Javascript since the time stamp on the cookie would be out of sync with the other cookies otherwise this was all cookies will be updated and set/kept with the same time stamps.
