notifications: improve response time when number of notifications is large

NotificationsController always retrieved materialized list of all notifications
in database, even to display only 10 of them. This is improved by feeding
SQLAlchemy Query object directly to webhelpers.paginate.Page, avoiding eager
load of all notifications.
