Security: Escape more strings

The sqlite3_ruby database adapter does not correctly taint strings
unless you first apply this patch:

  http://rubyforge.org/tracker/index.php?func=detail&aid=20325&group_id=254&atid=1045

With this patch applied, SafeERB finds more errors.  These are now
fixed.  It would be highly desirable to update SafeERB and modify it for
production use with Rails 2.2.
