.nvmrc support for `nvm use`

[Piotr Witek]

when invoking nvm use with .nvmrc got the following error:

> nvm use                                                                         13:53:05

He's actually maintaining but just ignoring this issue (i.e. the entire reason nvm is useful). :^)

@corysimmons a more productive comment would have been "Hey, could this be done now?", but instead you decided to assume bad intent and call the project useless.

I don't remember seeing this issue before now. It seems like a fine thing to support, but I have less interest in doing open source when people are rude.

If you would like to make this project "useful", please send a PR.
