Add a new entry to the package actions box that allows for filing
deletion and orphan requests. When choosing that action, the user is
redirected to a new page that allows for selecting a request type and
entering a comment. When submitting the request, a new entry in the
request database is created and an email is sent to a configurable
mailing list (defaults to aur-general).
