Bug 17404: Patron deletion page: Fix title and breadcrumb

Bug 17404: Patron deletion page: Fix title and breadcrumb

Title and breadcrumb of patron deletion page (deletemember.pl) say:
"Can't Delete Patron". This should be changed to "Delete patron".

To verify:
- Go to a patron's detail page
- Toolbar : More : Delete
Result: You get a question: "Are you sure...", but title and breadcrumb say:
  "Can't Delete Patron" rsp "Cant delete patron"

To test:
- Apply patch
- Repeat steps above.
- Verify that title and breadcrumb display properly, including patron's name
