Linux target and port

[yvanoff]

I have modified the Main.hx so it runs on Linux (should run on Mac as well) and can package Linux application. Additionally I have included Windows files in the redistFiles folder so Windows targets can be compiled from a Linux system

(This is the first time I'm making a pull request, I'm not too used to using git or making code used by others, don't hesitate to tell me anything that might be wrong with my code)
