Authentication issues

[haruska]

"remember me" cookies don't seem persistent on safari. there is also the issue of the link being captured by gmail app. need to rethink general authentication and maybe move to a more traditional username/password model in devise. People would have to go through the "forgotten password" flow. Could possibly send out links next year with that imbedded.

Might also want a way to "sign up" but that must be approved by the admin. Would eliminate needing to invite people. Maybe a free-form text of "who invited you"

ToDo:

• set rememberable and timeoutable module config
• set validatable config
• Format Errors
• Forgotten password flow
