When the server was being built on systems other than Windows, that system's version of node was being downloaded for the build instead of the expected versions (Win/x64). This change hardcodes the values so that they're no longer dynamically pulled from the current system. Should help with generating automated builds.
Also, re-enabled the build step that added the icon to the Windows executable. It was being skipped over on non-Windows platforms and I don't know why... it should be a cross-platform solution.
