Add build flair

Dearest Reviewer

I have add the travis-ci build badge to the README. I pushed the image down towards the bottom. I was thinking that most people reading the readme do not care about the build status. I have seen the badge done in different locations and with different titles. I am easy on where it goes. I added it because I found that I was looking for the status when my branch was failing. I have since learned the travis interface.
