Taxonomic Search Engine back online

My Taxonomic Search Engine is back online (mostly). This tool to search multiple databases for scientific names was another casualty of hacking. Having been developed under PHP 4, it needed some work to play nice with PHP 5. The changes were minor, and mainly concerned changes in code involving XPath and XSLT. I've commited these changes to SourceForge. I've not got the Species 2000 service back up (this needs local data to be restored), and the LSIDs are broken due to problems with IBM's LSID perl stack on my Fedora Core 4 machine (sigh).
