Improving DaveyP’s HIP link tracker

DaveyP came up with a nice way of logging outgoing links from 856 tags.

I’ve improved it, at least as far as our needs are concerned:

• If the user is behind a proxy that sends the HTTP X-Forwarded-For header, we record the user’s real IP address.
• Since we have more than one HIP server, we record the name of the HIP server.
• Since our profiles represent individual autonomous libraries who are much more interested in their own users, we record the profile code.
• Timestamps are now in ISO 8601 format.

You can get what I’m audaciously calling version 1.10 here: http://www.tblc.org/~ostrowb/hiplink-1.10.pl.txt
