Added a new JSON version task to my VSTS Version Extension

In response to requests on the VSTS Marketplace I have added a pair of tasks to added/edit entries in a .JSON format files.

The first is for adding a version to a file like a package.json file e.g.

{
"name": "myapp",
"version": "1.0.0",
"license": "MIT"
}

The second is designed for angular environment.ts file e.g.

export const environment = {
production: true,
version: '1.0.0.0'
};

But I bet people find other uses, they always do.

You can find the extension in the marketplace, you need 1.31.x or later to see the new versioner tasks
