LP1160596 - Add pagination for items in My Lists

Added pagination with page numbers when viewing the items in
a list.  Also made the number of list items per page a user
setting, per the suggestions of Pasi Kallinen and Jason
Stephenson.

The setting is located in, Account Preferences -> My Lists Preferences

Update: Added i18n part to allow for translation.  Removed hard-coded
bre.source.
