high sierra compatibility
improved nstask execution
alleviated need for 'sudo'
refactored code to find camera/mic process
pushed various XPC intensive stuff into background
wrapped debug statements with #ifdef DEBUG
improved NSTask to (hopefully) avoid hangs
added dictionary of activation alerts to help with deactivation alert logic
when no consumer process is found, still alert user that camera started
main app now launched via hardcoded path (again to avoid issues w/ 'App Translocation'
minor code cleanup
stop/start login item
set file perms correctly (i.e. setuid on login item)
update ui window
removed XPC embedded in main app (only is needed in helper.app)
