Configured build steps
Improved page load
Just merged my biggest PR ever in this project! The configuration used in this project was somewhat dated and not working very well, so I upgraded the nesscary tools to latest and configured in a way that's more perfomant & smaller.

Now I can hapilly work with nicely-working source maps ❤️ Users would love smaller binary size too.
