Since the client side code and server side code run independently, the
docker compose process needed to be updated to reflect this change.
This fix included updating the docker-compose files' versions.
* Improved docker, bower
* npm install missing mocha
* Fix for 'npm install -g npm@4' not resulting in a functional npm
* Improve speed of 'docker start' by withholding directories not used by image environment
* Reverting changes to bower.json
- added docker-compose.yml for quick one-command spinup
- added docker-compose.dev.yml to override /habitrpg mount
- modified Dockerfile to accept /habitrpg mount
