Notifications: Edited notifications data access objects, so as they return an object with id defined, when save{object} methods are called from notificationsManager.
RPC: Edited NotificationManagerMethod, so as it passes the returned object in saving methods.
Merge pull request #27 from jirmauritz/notifications_Java

Notifications: Methods for saving object to DB return that object with ID set. (also changed in RPC)
Do not use ident for java files (in .gitattributes)
