[osx] - remove XBMCHelper binary from tree
[XBMCHelper] - change to only build i386 and adapt output dir to match the one where the binary was in our tree before...
[XBMCHelper] - small refactor - move the launchagent installation/deinstallation out into its own method
[osx] - add callback when the input.appleremotealwayson setting is changed ("allow startup of kodi via remote") - to instantly install/deinstall the launchagent -> needed for manual migration path from xbmc to kodi
