! Cast the user id to an int when we first get it set up because that's the right thing to do. Essentially as per #338 and #355 but without any edit conflicts.
! Add a new hook for cache cleaning as per #381.
! Brought the profile/show drafts to look the same as show posts, in terms of providing a description and the extra header for sidebar mode.
