  This change fixes: 1) MPII-878 by applying the same ordering to the "phenotypes" HTML table and download stream rows for gene and phenotype pages; and 2) almost fixes MPII-876 ;and MPII-877 by replacing the graph link hostname hard-coded from the solrUrl value in the properties file with a reference to baseUrl. The latest change prepends the baseURL which makes the link in the download file perfect except that the hostname is missing. I expect to fix that tomorrow.
