Ability to add custom function for version compare

[Arti3DPlayer]

I have a version that looks like: "version": "0.256.00", and your lib says me that i have incorrect version... It will be cool to improve compare:

or add ability to use custom function

A bit unusual request. I'm using official npm module SEMVER https://github.com/npm/node-semver

semver.gt( remoteManifest.version, this.manifest.version )

It's kinda de facto standard. But ok, why not. I'm going to think about

I don't know why all use semver library if it is better just use own function on 30 lines and remove dependency :)

Because it's a standard with clear specification, meaning I can rely on it. I guess we can close this one.
