Email verification should expire after 30 days and forgot password verification should expire after 7.

Things that should be done:

• These fields should be added but not required
• Views should be modified to add these expiration fields when adding the tokens
• Views should be modified to check the expiration fields before using
• A migration should be added...
  • fields without verification keys should just have the email_verification_expires and/or fp_verification_expires set to None
  • fields with verification keys should set them to a timedelta from today

You can set these fields via a timedelta:

>>> import datetime
>>> datetime.datetime.now() + datetime.timedelta(days=10)
datetime.datetime(2011, 7, 4, 8, 41, 8, 502139)

New users should be requested email verification.

Steps to make happen:

• user['status'] should default to 'needs_email_verification'
• After registering, a property should be set with a unique random verification key
• Link embedding verification key and username should be emailed to user
• Clicking the link should activate the user's account, setting user['status'] to active

Users should be able to mark media entries as favorites by clicking a button/link in the entry detail view (and probably from gallery views as well). This change will likely require the creation of a new "UserFavorite" model with a structure like:

{'user': user_id, 'media_entry': media_entry_id, 'created': datetime.datetime.now()}

...and also a new field on MediaEntry containing a count of UserFavorites for that entry (to avoid expensive queries to generate this number dynamically for every request).
