* Adds Dist Trusty and Sudo Required

As Per Travis CI docs 

> When specifying sudo: required, Travis CI runs each build in an isolated Google Compute Engine virtual machine that offer a vanilla build environment for every build.

This has the advantage that no state persists between builds, offering a clean slate and making sure that your tests run in an environment built from scratch.

Builds have access to a variety of services for data storage and messaging, and can install anything that’s required for them to run.
