Re: Nim to the browser with WebAssembly 1.0

@vic1107: Emscripten must be installed so that its compiler is found (through 
the PATH environment var I think), didn't mention that in my original post. 
Since I did this on Linux and You seem to be on Windows, changing some settings 
may be necessary. The compiler user guide probably has some info. Knowing 
nothing about Nim on Win, I would just try to append .exe to the values of 
clang.exe and clang.linkerexe, which is probably wrong.
