Bug 6254: make it possible to set default privacy setting for new patrons

There is currently no way to set the privacy setting for newly created
patrons. This patch adds a new field "default privacy" to the patron
categories such that each patron category may have a different default
privacy setting.

Test Plan:
1) Apply this patch
2) Edit a patron category, change the default privacy to "forever"
3) Create a new patron of that category
4) Log into the catalog as that patron, verify the privacy setting
   is set to "forever"
5) Repeat steps 2-4 with the settings "never" and "default"
