Bug 22429: Infinite loop in patron card printing

Text fields in Patron Card Text Layouts can contain regular
expression metacharacters, which - instead of being treated as
literal values - are interpreted and prevent line wrapping. This
causes the process to get stuck in an infinite loop, which keeps
running even after the web server has timed out (at least when
using CGI).

This patch escapes the relevant input from the text field so the
regular expression substitution treats characters as literals
instead of as metacharacters.
