Android:

* Re-create RockboxFramebuffer instance with every time there's a new Activity.
* Also, allow Rockbox to be started via multimedia buttons, immediately starting playback if wanted.

We don't need to keep the fb instance around when it backround, and it makes us less depending on it and the activity (less race conditions). And this is how you usually do it in Android apps.
