Bug 15211: adding Tools section sidebar to label creator

The label creator had a very sad sidebar, it needed to have the Tools area sidebar on it.

To test:

Click through all "New" pages, verify that the sidebar appears
Click through all "Manage" pages, verify that the sidebar appears.

Also verify that "Label creator" is bolded in the toolbar while the label creator is active.
