Allow to install multiple binaries

[silverkorn]

Related NW.js issue:
nwjs/npm-installer#47

I was wondering if the electron prebuilt could install multiple binaries for different operating systems in a same place, so, by suggestion, by modifying the path of ./electron-prebuilt/dist/ to ./eletron-prebuilt/dist/win32-x64/, ./eletron-prebuilt/dist/win32-ia32/, ./eletron-prebuilt/dist/linux-x64/, ./eletron-prebuilt/dist/darwin-x64/ and so on so it could be dynamically set with process.platform & process.arch.

Please, see my request for NW.js via their npm installer for details about the motivation.
Thank you!
