Enables the use of WindowsToaster when using WSL

[rmobis]

This uses the very simple is-wsl package to check when node is being run under WSL (Windows Subsystem for Linux) and instead of using Linux's NotifySend notifier (which doesn't work) uses WindowsToaster.

Without this change, notifications inside WSL don't popup on Windows.

Guys, anything that needs to be improved here?

[mikaelbr]

Oh. Thanks! Hadn't even considered this an issue. Thanks!

[rmobis]

I just noticed, we might have to update DECISION_FLOW.md to reflect these changes.

Any idea when a new release will be rolled out with this change added? Very keen to start using it.

[rmobis]

Been waiting for a while for a new release too. In the meantime, if node-notifier is a direct dependency of your project you may use my fork in your package.json like this:

"node-notifier": "github:rmobis/node-notifier"

Or, if you're using it through webpack-build-notifier, I've also made a fork of it simply to use my fork of node-notifier. You can also use it in your package.json like this:

"webpack-build-notifier": "github:rmobis/webpack-build-notifier"

Hi! New version out now:

node-notifier@5.4.0

(also you could have used this current version by doing npm i mikaelbr/node-notifier without using a fork)

[rmobis]

Thanks!

(You're right; I made the fork of webpack-build-notifier before this PR was merged and after that I completely forgot about it)
