Building self contained libraries

[houmain]

I would like to use WAjic for compiling C++ libraries to JavaScript. Using one of these works fine, but when multiple scripts are used together they seem to conflict. As far as I can tell, it works flawlessly when each script file creates its own WA object instead of using a global one. In my case, where I do not want to redirect the output, this would be a nice option.

Thank you very much for this fantastic tool! Being dependent on Emscripten was never an option for me. In this project I am using it extensively: https://github.com/houmain/crown
