Adding support to install nodejs to windows node from package

This is an effort to add support for installing nodejs to a windows chef node. I took the approach of integrating with your current recipes, as opposed to adding a new one. perhaps some day there could be support for installing to windows from binary and from source, as well.

I see some options besides the one I implemented in default.rb (including the install_from_package recipe, then returning):

- we could require windows nodes to use a role attribute to change the install_method from default value of 'source', then default.rb recipe can remain unchanged. This is the most robust, allowing for future recipe changes to support install from source and binary for windows.

- we could merely overwrite the install_method attribute in default.rb, then not return and let the recipe get included from the same point as for the linux platforms.
