npm-version: add beta suffix to version

[damianobarbati]

Would it be possible to add flags through npm version patch|minor|major?

I.E:

$ cat package.json | grep version
"version": "v1.0.5",
$ npm version patch --suffix beta
v1.0.6-beta.1 # patch and beta is incremented
$ npm version patch --suffix beta
v1.0.6-beta.2 # beta is incremented

Currently we have just npm dist which add the beta flag when publishing to npm but it doesn't properly update version in package.json

Any idea?

Probably just with some helper module.
