Title: Alert block heading style

I find myself restyling a bit the alert-block heading for a project, I though it's looks cool so i made a PR.

Add a class .alert-heading for markup consistency with the new panel components in v3. Like the panel heading it can now be apply to a div or any heading element as well.
