New configuration options were added to to control where the sitemaps are written and hw often they are updated. By default we do it once a day, as more often is overkill for search engines.
Included a JUnit unit test to test the Sitemap generation functionality.
Included changes to MetaCatServlet to sched...

01:10 PM Revision 3221 (metacat): paging now works well. sped up the caching by using SAX instead of DOM parsing. it seems fast. need some other people to test for me though. the two params needed are 'pagesize' and 'pagestart'.
