Added Visual Studio to Software and example link to schemastore.org

Visual Studio 2013 now fully support auto-completion and description/type tooltips for any JSON document that's paired with/pointing to a JSON schema. 

---------------------------------------------

Under examples, a new link has been added at the bottom pointing to schemastore.org. This website contains several JSON schema files for popular JSON documents, such as `package.json`, `.jshintrc` and `bower.json`. It's a great place to learn about some real-world JSON schema files that are being actively used today.
