Bug 21211: Add patron toolbar to suggestions, discharges and ill requests tabs

When paging through the patron account in staff, using the tabs on
the right, you notice that some pages are missing the patron toolbar
on top and that the headings, where they exist, vary in size.

This patch adds the patron toolbar to 3 more tabs and changes headings
to h1 to be consistent with older tabs. It has also been suggested on
another tab that this is preferrable for screen readers.

Note: Modification log was left out for now, as this is also used in tools.

To test:
- Activate ILL (ILLModule pref)
- Activate discharges (UseDischarge pref)
- Go to any patron account, tab through the tabs...
- Verify that discharge, purchase suggestions and ill requests are
  missing the toolbar
- Apply patch
- Verify that the toolbar now appears on these pages and works
  correctly
- Also veriy that the headings are now consistently h1 on all pages
