Names for modules in subfolders use wrong slashes on windows

[AmyAmy]

generates the following name: define("components\new\file"
should be define("components/new/file",

seems like an easy fix

moduleName = moduleName.replace(/\\/g, "/");
after the
var moduleName = path.join(path.dirname(filepath), path.basename(filepath,extension));
seems to do the trick, not sure if that's the proper way to do that tho
