[atv2] - fix learned remote buttons for fwd and rewind ios 6.1 (atv2 5.2) - apple changed the values for those for filling a gap in the enum i guess. Also those 2 buttons are repeatable - so handle them right for not firing 2 messages for one keypress (press, release)
[osx/ios] - adapted README.osx and README.ios for usage with new unified depends
[CA/AE] - make the devicelist change callback more robust - should fix crashes during shutdown on some system constellations (where removing the callback seems to also triggers the callback at the same time)
