Rig up basic start/stop functionality
Add ids to start/stop buttons
Reorganize project structure, add classes and ids

I made several changes to the structure of the
project. I moved Brents images and psd folders out
of the root and into the assets directory.

I also removed normalize.css, as I believe
bootstrap does normalization for you.

startButton and stopButton ids were also added to
the buttons. These ids will be the handles used in
the backend code.

I also rigged up some basic animations for the
start and stop buttons. The stop button will be
hidden on initial pageload. Once the timer is
started, the start button fades out and the
stop button fades in. When the stop button is
clicked, the word "stop" changes to "reset" and
the start button appears again.

Note that the UI interactions are still extremely
buggy and will require us both sitting down
together for an hour or two one evening hacking
away at polishing this turd.
Improve button animation and hide stop initially
Add UI and style elements
