Show 'next' version number.

[RafalFilipek]

Hi!
It would be nice if you could only get the next version number, without updating package files.
Maybe something like:

mversion [ <newversion> | major | minor | patch | prerelease ] [--show -s]

Thanks for your work. Excellent project :)

Hi and thanks for your input!

So your thinking a "dry run", so if you have v1.0.0 now and do:

$ mversion minor -s
v1.1.0

or

$ mversion prerelease -s
v1.0.0-1

You can already get the current version and do this mentally, but we could always add an option if we feel like this adds good value.

$ mversion
package.json: 1.0.0

Exactly! It would be very useful in few cases:

• automation tools (eg. you have to prepare something in your environment for new version)
• tools with user interface (like WWW)
• console tools (like ./i-dont-know-git-but-i-want-to-push-my-work-and-tag-it ;))
