Using resgen as a HiGlass track source server

HiGlass uses track source servers to list available data when adding a track. Users in resgen can provide track source servers which list and serve all the data in the user's project. This is accomplished by adding the url https://resgen.io/api/v1/gt/<username> to the viewconf loaded by HiGlass.

For example, the paper-data group is used as a track source server on the https://higlass.io deployment. This can be verified by going to https://higlass.io/app and editing the viewconf.

  "trackSourceServers": [
    "//higlass.io/api/v1",
    "https://resgen.io/api/v1/gt/paper-data"
  ],

If you have a local higlass instance and wish to add a resgen.io track source server to the default viewconf, use the admin panel at http://my.higlass.deployment/admin, going "View confs" and editing the entry with the UUID of default to include the appropriate resgen url.
