DroidEssentials updated

Updated DroidEssentials today.

1. Removed some redundant classes to make it a bit leaner.
2. When you start the app, it will only start the service if you have ticked the box - previouslyit always started the service.
3. When you start the service, it no longer tries to start the same service several times (oops!). This had no effect other than wasting some time.
4. Touched up some of the notification icons - the low battery looked a bit weak and the full battery had no transparent background.
5. The app used to wait a minute after a boot had finished before it the service was started. I've removed the 1 minute pause as the starting of the service doesn't take much time or cpu so no need to wait.

Hope you like the updates.
