Support node 12

[ipy]

win-mouse uses Handle which is removed from the latest v8 version and causes build failure. Could be fixed like node-iconv did.

I'm using the electron-drag npm package which uses win-mouse under the hood. I'm also getting a similar error when a npm post installer for my electron app runs electron-builder install-app-deps and I'm using node -v =10.15.3. Did you manage to get your code working on a specific node version @ipy

Pushed a modified version for node 12 https://github.com/ipy/win-mouse

Thank you, works great with Electron 5.0.1
