Multiple Notification Fix

Modified PrivacyNotificationHandler to include unique NotificationId in
Intent so multiple notification can be generated without replacing each
other.
Modified DBInterface to include query to draw RowID (_ID) for package name, this is used as the unique identifier in the intent and notification.

Installed and tested and it functioned correctly, I installed 6 programs via restore from Titanium Backup and 2 x apk's all generated individual notification without overriding the initial notification. Also each notification correctly opens the displayed application when selected.
