v0.8.6

Added

• Allow overridden user models to skip email/password validations
  conditionally. This makes username/facebook integration easier.

Fixed

• Clearance features capitalization should match view text.
• Skip :authenticate before_filter in controllers so apps can easily
  authenticate a whole site without subclassing.
• Added randomness to token and salt generation,
• Reset the remember_token on sign out instead of sign in. Allows for the same
  user to sign in from two locations at once.
• Append the version number to generated update migrations.
