win,install: only download target_arch node.lib
Browse files Browse the repository at this point in the history 
Instead of downloading node.lib for all architectures, just download the
one that will be needed. Install.js changed to enable downloading just
node.lib for node versions that already have tarball downloaded and
extracted. Not fetching lib now fails the installation. Increased
installVersion because of the changes.
