Processes hanging around after electron app quits

[samdjstevens]

I believe I have discovered a bug where processes remain hanging around after the electron app quits when using/issuing a notification using this package.

I think this is because the window object is never destroyed?

Any help would be much appreciated!

Whoopsie, looks like you are right! Thanks for the report @samdjstevens.

I'm not sure when i will get to provide a fix, are you up for a PR?

I've had a quick attempt at fixing by listening for electron quit events and destroying the window/clearing the var but no luck yet - will hopefully get a bit more time to investigate soon.

It would make sense killing the browser process after we don't need it anymore, so in the onClick/onClose callback handlers.
