uribl plugin - trivial patch

Hi all,

Finally got some time over the holidays to play with qpsmtpd - whilst doing so I noticed what I believe to be a tiny bug in the uribl plug-in that ships with qpsmtpd.

I wasn't sure where to post the patch; so I guessed that here was as good as place as any.

See attached.  The patch skips to the next line in the case of quoted-printable continuations; this is to save a few CPU cycles and prevent the possibility of a partial match of a URI.

Kind regards,
Steve.
