Issue #2 - Mobile Responsive

I aligned the text within the Bootstrap .jumbotron, so when it is viewed on a smaller device the text is neatly formatted in the viewport. In addition, I added the .btn-lg and .btn-block Bootstrap classes to the buttons within the .jumbotron and added a margining of 5px going around the radius of the button. Finally, I did a little code clean up and got rid of additional spacing and tabs.
