make 'include-once' really "download source once per-instance"
Marc's implementation would only ever process the include-once urls a single
time. This changes that to process them every time, with the second time
coming from a file on disk rather than the url.
You can then do expiring or one time use URLs in the include-once and
have all function of if the content was there every time.
The cached file is readable by root-only.
