Make Google Closure Compiler implementation selectable

[arichiardi]

Hi Antonio!

This is an idea that actually really excites me and therefore I would like to share it here!
I have recently discovered that the GCC offers a way better way to work from node: https://www.npmjs.com/package/google-closure-compiler#native-node-usage-for-plugin-authors

There are many versions available now and for sure the GWT-transpiled version is the least supported at the moment.

What if lumo could just detect (and/or configure) which GCC implementation is installed in the system?

This would allow to use the JVM or native version in case they are present.

A developer would have fast startup time and only "willingly" paying the price of the JVM startup for the optimization step.

Wouldn't that be amazing? Do you think it is doable? 😄
