FFmpeg / build improvements

 - added PostBuild target to copy ffmpeg.exe to the build folder;
 - updated the installer file to remove ffmpeg.exe as it is picked from the build folder instead;
 - both InstallerOutput and FFmpeg folders are now created on git checkout, but their content is ignored by the version control.
