Simplify the generation of hgGateway's dbDbTaxonomy tree info and support mirrors better: new hg.conf setting hgGateway.dbDbTaxonomy enables tree display and specifies relative URL to file.  Instead of dbDbTaxonomy.{hgwdev,rr}.js, there is only one dbDbTaxonomy.js, built from hgcentraltest (hgwdev).  hgGateway.c's HTML output includes JS encoding the set of active genomes+taxIds.  hgGateway.js uses that to prune the tree so it contains only active genomes; now we can use the hgwdev tree on the RR and see only RR species.  Also updated dbDbTaxonomy.js to get the latest hgwdev species as of 4/18/16.
