Title: Use symlinks instead of copying files upon switch

Backward incompatible change - any modules and executables
such as npm, coffee and even n itself are now different
for different node versions.

This is probably a good thing anyway. At least you won't get something like
"npm won't work with your node 0.8.11, install 0.6, please"
