Title: disable output of version on `use` and `run`

When using `nvm run` or the `nvm-exec` script from other scripts (in my case an ansible playbook) which depend on the actual output (`nvm-exec npm list --json`) the `Now using node $VERSION` part breaks this kind of usage.

So this removes this feedback.

Also, I've redirect all echo output of errors to stderr (`> &2`)
