also improve favicon updating to not change if we're same as previous
not sure how intensive the nativeImage stuff is but cheap efficiency
For FLASH FLASH I moved the setBadgeCount stuff RPC -> IPC
should be more reliable now, its in electron-main
Win only:
if mainWindow is set and is not in focus make it FLASH
clear flash if notification gets cleared elsewhere
debounce focus handler so we don't set a million of them
if the app is backgrounded a while
