mod_http_oauth2: Use more compact IDs
UUIDs are nice but so verbose!
The reduction in entropy for the nonce should be fine since the
timestamp is also counts towards this, and it changes every second
(modulo clock shenanigans), so the chances of someone managing to get
the same client_secret by registering with the same information at the
same time as another entity should be negligible.
