Mailer should give self as payload because it contains all the information needed (as the template rendered and the mailer name).

  validates :email, :presence => true, :format => /@/
  validates :genre, :inclusion => %w(m f)
  validates :password, :length => 6..20

Compile length validator options still at the class level, so whenever the validator is called, it just needs to check for :maximum, :minimum and :is values.

Fixed that fragment caching should return a cache hit as html_safe (or it would all just get escaped) [DHH]

Restore the connection method which was added so it can be overridden.
