Bug 12349: Show card number in detailled suggestion pages

This patch modifies the main suggestion management page to link patron
names to their details rather than with a "mailto:" link.

This patch also includes the following changes:

- A fix for Bug 18154, Show card number in suggestion details view.
- Changes for brevity to labels in the suggestion details & edit view.
- Addition of the datepicker class to date fields in the suggestion edit
  view.
