Merge branch 'master' into kpam-iter4
delete functionality works

deleting now works from the dashboard as well as the editor. if the
editor page is on a not previously saved stage, the delete button does
not show via templating

unsure about safety of delete--doesnt do much checking/authentication.
someone could theoretically send post request via curl to delete stages

there should be a secondary check like "Are you sure you want to delete
this?"
