Linux/Windows support

[artemyarulin]

Due to the fact that we are using Planck under the hood only MacOS is supported for now.

There is a work in progress of writing Planck 2.0 using C so it will work on Linux machines as well (actually beta version is available already)

Another solution could be rewriting build.cljs to use simple CLJS and run it with NodeJS. It's not a big deal, maybe some IO functions gonna behave differently, but nothing dramatically.

As I'm currently using heavily ReactNative and MacOS is needed in any case I'll postpone with solution for this problem.

If you are interesting in this, need some support or if it's a show stopper for you - feel free to ping me, we will figure it out
