Yarn extension for Chassis

The Yarn extension automatically sets up your Chassis instance to be able to use yarn inside your Chassis box.

# In your Chassis dir:
git clone --recursive https://github.com/Chassis/Yarn.git extensions/yarn

Then you'll need to reprovision

cd ..
vagrant provision

Alternatively you can add the extension to one of your yaml config files. e.g.

# Extensions
#
# Install a list of extensions automatically
extensions:
    - chassis/yarn

Then you'll need to reprovision

vagrant provision

Yarn has now been installed inside your Chassis box.
