text: Title: Allow nicer urls for charts, instead of (or alongside) UUID
  Body: This is a potentially hazardous change, as the idea of a guid is to prevent collisions in the name. Some potential ways to achieve this:
  
  namespaced charts (e.g. SOMEUSER, or SOMEGROUP) that ties into the existing auth mechanism, or is an arbitrary field in the chart.
  
  The originally UUID link should always work however, and should be the default if there is no other way to get a URL.
