Bug 8387: Hide headings in tools when user has no permissions for any listed below

The headings for each column on the tools page will show, even if the
user has no permission for any tool below it. This patch tries to
correct this.

To test:
- Try various combinations of tool permissions
- On the tools module start page and for the tools sidebar
  visible on the left on a tool's page:
  - Make sure headings don't show when you have no permissions
    for any of the tools listed below
  - Make sure headings show correctly if you have one or
    many of the tools permissions needed

The qa tool gives some warnings but I think they can be considered false
positives.
