mdv36 release further update

The "correction" in the previous release was necessary because the production portal was pointing to an old DB. This update restores the GWAS_Leptin_eu data page that is necessary for the current version of mdv36.

This update also includes updated css from DK that formats the GRS page as a standalone page rather than as a page section. This change is transparent to users.

Date is date of deployment; e569a49 is git repo number of KB code.
