Installation problem on linux. Missing libgtk-3-dev.

When I tried to install proton-native with npm i -S proton-native like the quick-start guide suggests I got this error:

> npm i -S proton-native

My machine has Linux Mint 18.3 installed which is based on ubuntu 16.04.
After some searching in the web I found out that I have to sudo apt-get install build-essential libgtk-3-dev. Now it works. Maybe you could add this info to the guide so that others can have an easier start with your framework. Maybe something like a preconditions paragraph?

I will add this, but I'm really busy at the moment. If you have time you're free to submit a PR. Thanks.

Thank you! I've had this exact same error for awhile.
