More improvements in the change info block UI

On the project settings icon's tooltip, instead of saying "Go to
project", which is a bit ambiguous, say "Go to project settings".

Instead of linking the project name to the project's default dashboard,
link to a project query.

Add a new dashboard icon (from [1]) that links to the dashboard.
