As a contributor of Nutrition Information API, I want the build status badge to be on README.md, so I can quickly see whether the build is passing or failing without looking at the build service.

Acceptance Criteria

Given a build, when it passes, display a Build Passing badge on README.md
Given a build, when it failes, display a Build Failing badge on README.md

Test Plan Perform acceptance criteria on a contributor's fork.

Dev Work Update README.md to have the following below the first heading.

[![Build Status](https://travis-ci.org/NutritionMate/Nutrition.Information.Api.svg?branch=master)](https://travis-ci.org/NutritionMate/Nutrition.Information.Api)
