Bug 30807: Migrate to patron-title in pay and paycollect

Bug 30807: Migrate to patron-title in pay and paycollect

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 their accounts tab
2) Note how the patron name displays in the title, breadcrumb and
   headings
3) Click through to make a payment
4) Note how the patron name displays in the title, breadcrumb and
   headings
5) Apply the patch and reload the page
6) Confirm the patron name still appears in each location and is
   consistently formatted and linked as you would expect

Note: This patch also removes a superflous hidden title form element
that was simply passed to and from the controller but not actually used
in any way.
