Updating sound file section as e.soundname doesn't work on Fire OS. Probably should test it though.

New nodeJS based server script to test amazon ADM push notification services.

Align correctly tabs.

Added server script and readme for Amazon Device Messaging.

Added server script and readme for Amazon Device Messaging.

* Don't check if we are in the foreground - that happens anyway in the
sendExtras() method (https://github.com/phonegap-build/PushPlugin/blob/master/src/android/com/plugin/gcm/PushPlugin.java#L111)
* Only display a message if the message has text to be displayed

Fixes #52 and undoes #3

* Put all the plugin code in the plugin namespace: com.plugin.gcm;
* Renamed to namespace GCM to gcm, namespaces should be lower case
according to the java style guidelines;
* Deleted the google gcm code and added gcm.jar instead;
* Added CordovaGCMBroadcastReceiver.java to enable GCMIntentService to
be namespaced in the plugin namespace instead of the client project
(which is is the default with google's GCMIntentService);
* Moved all java <--> javascript interop to PushPlugin;
* Moved all notification code to GCMIntentService (maybe this fits
better in its own class);
* Changed the way the plugin detects cold starts in order for it not to
crash when the back button is used to navigate out of the app;
* Changed the caching on the filesystem to a memory cache on a static
variable, which increases performance and simplifies code;
* Cut up some code into separate methods ;
* Added code comments;
* Updated the readme file.

You need to add android.permission.GET_TASKS. 
Without this permission, the application crashes when it receives PUSH NOTIFICATION.
