Link dashboard title to a url version of itself

When using a stable project dashboard URL, the url
obfuscates the content of the dashboard which can make
it hard to debug a dashboard or copy and modify it.  In
the special case of stable dashboards, make the title a
link to an unstable url version of the dashboard with the
url reflecting the actual dashboard contents the way a
custom dashboard does.
