Bug 2310: display tooltips explaining why patron menu items are disabled

With some staff client menus options are displayed as disabled when the
logged in user doesn't have permission to perform that function. This
patch adds Bootstrap tooltips to patron menu items with text explaining
why they are disabled.

To test, log in as a user who lacks permission to modify patrons or set
permissions. Open a patron record in circulation or patrons. Hovering
over renew, delete, and set permissions links (in the patron toolbar
"More" menu) should trigger a tooltip with a brief explanation.

Test the "Update child to adult patron" link by viewing an adult patron.

A separate patch will address catalog menu items.
