Add script to easily execute tugboat commands

[robertragas]

Added a small bash script to easily execute tugboat stuff without the need to go into the web terminal interface and remember all those commands. This should also prevent people from using the Drupal Module Interface to enable modules which can time-out.

All you need to do is install the tugboat cli with

brew tap tugboatqa/tugboat
brew install tugboat-cli

and setup an access token on
https://dashboard.tugboatqa.com/access-tokens
When you then run the script for the first time it will ask you for this access-token.
bash social-tugboat.sh
After that you are able to enable modules, runs custom drush commands or download the database locally.

Let's get it in and start using it. We can iterate on it later 👍

Nice one @robertragas!
