Add a new 'SignoffSpecification' model which will capture metadata
regarding a specific package if it differs from the norm- e.g. more or
less than 2 required signoffs, is known to be bad, a comment from the
maintainer, etc. The groundwork is laid here; much of this will still
need to be wired up in the future.
Enhance the view with a lot more JS prettiness and add revoking of
signoffs. The signoff page can be filtered and the links and all the fun
stuff are totally dynamic now.
