[feature] Add `run` command 

`run` command runs given node version without modyfing global state:

    [maciej@PC07 nvm (run)]$ node --version
    v0.4.12
    [maciej@PC07 nvm (run)]$ nvm run 0.4.12
    Running node v0.4.12
    > process.version
    'v0.4.12'
    > [maciej@PC07 nvm (run)]$ nvm run 0.5.9
    Running node v0.5.9
    > process.version
    'v0.5.9'
    > [maciej@PC07 nvm (run)]$ node --version
    v0.4.12
master
