add new video/audio presence icons in the framework resource dirs, and make them public.

- add definitions for

presence_video_away
presence_video_busy
presence_video_online
presence_audio_away
presence_audio_busy
presence_audio_online

in the public.xml, and update current.xml

- the actual icons for the audio versions are not yet done, so I used the video versions as placeholders.
