Microformat support:

Needed to restore OpenSearch capabilities, and did the following while
I was at it:

  * add support for unAPI: http://unapi.info/
  * add basic support for COinS and OpenURL:
    http://ocoins.info;
    http://www.niso.org/committees/committee_ax.html
  * ^^ Gives us Zotero Support!
  * adding some XSLT stylesheets for handling additional transformations
    NOTE: English and MARC21 specific unfortunately
  * adding back opensearch/rss feed <link>s for autodiscovery

TODO: after the installation, to get the Zebra system running on an external
port it's necessary to hand-edit the configs. I'm looking into Virtual Hosts
which could solve that problem (run on both the socket and a port).

Need to add better error handling to the unapi and opensearch scripts
