* AlarmReceiver.java: Removed. Now it's the service which will retrieve data.
* Core.java: The method of setting periodically data retrieval was changed.
Now, the AlarmManager will launch the Service instead of BroadcastReceiver.
* PandroidEventviewerService.java: Every time it receives a call from the AlarmManager, will search for new events.
* Most of files have little changes to adapt the new data retrieval subsystem.
