Travis-CI configuration

[Greg Roach]

Your travis builds are failing. e.g. https://travis-ci.org/Stolz/Assets/jobs/71597144

1. There is a message asking you to upgrade to the infrastructure. You should do this. It is much faster. Just add the line sudo: false to your .travis.yml.

2. Your .travis.yml fetches/installs composer. This is not necessary. Composer is already installed, and will be run automatically if a composer.json exists.

This is the config I use in my PHP projects

language: php
php:
  - 7.0
  - 5.6
  - 5.5
  - 5.4
  - 5.3
  - hhvm
sudo: false

Thanks for reporting Greg. It should be fixed now.
