Bug#805648: qa.debian.org: Provide a way to share an ignore list (for team dashboard)

[Asheesh Laroia]

One option is to store data in the window.location.hash (or equivalently
html5 pushstate).

See e.g.:

http://yuilibrary.com/yui/docs/router/

For docs on a library that uses this.

This avoids server-side storage and still gives permalinkable state.
