PlaybackState: Enable Actions

[fritsch]

We should properly identify the actions of the media session as well, cause SetActions needs them.

You also have to enable these constants in the header file

Oh indeed my bad, didn’t think about that. Thx for the catch!!
edit:
Do we really need to, though?
Seems they are just defined in the cpp file to avoid clashes with some core macros?
See:

libandroidjni/src/PlaybackState.h

Line 31 in e9ed532

/* Clash with internal macro

In order to be used from other classes they need to be in the header.
There should be no conflict if used in this way: CJNIPlaybackState::ACTION_PLAY

Thanks git add for the win ;-)

Let's keep it open for a bit - I want to fix the other bug for the MediaSession first and time is very limited.
