Subject: [PATCH] Change DELETE action from "*" to "delete"

With token authentication, requiring the "*" action for DELETE requests
makes it impossible to administratively lock a repository against pushes
and pulls but still allow deletion.  This change adds a new "delete"
action for DELETE requests to make that possible.
