Add a CLI command that generates the package.json "scripty"'s for you

[searls]

Idea being: by inspecting the file system of scripts/, you should be able to populate the "scripts" section of the package.json so folks don't have to manually keep package.json in sync manually.

On the other hand we could seek a more dynamic approach that'd allow scripty to intercept npm run without ever changing the package.json

For now i think the right thing to do is be explicit like we are being until we get some usage as feedback

Populating the "scripts" section of the package.json def has some niceties. Mainly:

• no need to know about scripty to be able to tell what a script does
• you can easily check what all the scripts do via npm run.

I had thought about making a tool that populated the "scripts" section, but never got to a point where I really needed it – I guess I've only used the "scripts" field with simple configs.

I'll try using scripty and report back in case I ever feel the need for this populater feature. :)

Thanks @dasilvacontin!
