Bug 31402: Update tools sidebar to match tools start page

This patch updates the tools sidebar so that it better matches the tools
home page:

- Sidebar menu should say Tags instead of Tag moderation
- Barcode image generator and Quick spine label creator links
  reversed.
- Upload any file -> Uploads
- Cash management section is added to sidebar using brief text

This patch does not make changes to the way plugins are displayed in the
sidebar. In order for the sidebar to correctly display according to the
presence of tool plugins I think some kind of global variable would need
to be set.
