* Added volume controls in Example app
* Fixed occasional COMException when using Get- or SetSpotifyVolume
This exception only happens if Spotify is using an audio device different from the default one. Such a thing is only possible (as of v1.0.75.483.g7ff4a0dc) when using the "--enable-audio-graph" command line argument, that makes available the "Playback device" advanced option in Spotify.
Changed Mute and UnMute function to work with both x86 and x64 processes on Windows 7 or newer
Added functions to manipulate the Volume Control of Spotify
