Overtone internal SuperCollider server not loading plugins

[chilliams]

I installed Overtone and it wasn't producing any sound when I used overtone.inst.piano.

It seems that the internal server isn't loading my SuperCollider plugins. As a workaround I have set :server :external in my ~/.overtone/config.clj

Steps to reproduce:

1. Follow the Quick Start Installation steps in the README.md
