Basics of setting up a new client

We need to have a checklist for what happens once we have agreed to partner with a client on a project.

This needs to be expanded into a comprehensive readme, but here is a start:
+ [ ] Create and sign contracts
+ [ ] Book initial workshop
+ [ ] Set up Google Drive
+ [ ] Set up Gitter channel
+ [ ] Create client org if one doesn't exist
+ [ ] Invite team members to org (client and dwyl team)
+ [ ] Create dwyl dev team
+ [ ] Create repo for the project, initialise with a description, readme and call it something intelligent
+ [ ] Copy over our labels
+ [ ] Ensure dwyl dev team has correct permissions in repo
