Fixes #64. Let admins destroy proposals.

Man, the admin pages are getting ugly. I should do something about that soon.
Fixes #63. Adds notes to admin review. Clens the layout of the admin list.

Easier to look at, leverage existing tools, DRY up notes a bit. Some handy stuff here.
Merge pull request #65 from jnf/jnf/destroy_proposals

Destroy Propals, Get Notes, Everybody is happy.
