**Other information:**
This PR is an update to the README file to include the Vue Land chat hosted by Discord. 😄  Although @egoist has mentioned the chat on Twitter I thought it'd be a good idea to include it in the README so new and old Vue developers know about the resource. Also, I added badges for both the Discord and Gitter chats.

_Since this PR made no changes to Vue's codebase I neglected to run any test._
