Bug 30806: Migrate to patron-title in member-flags

This patch updates the member-flags template to use the patron-title.inc
include wherever patron names are referenced.

Test plan
1) Navigate to a patron and click through to edit their permissions
2) Note how the patron name displays in the title, breadcrump and
   headings
3) Apply the patch and reload the page
4) Confirm the patron name still appears in each location and is
   consistently formatted and linked as you would expect
