Restart button to go back to homepage options about snapwat

Hello,
You can add this line :
<button id="link-home" class="btn-back"><img src="images/iconic/arrow-left.svg" alt="Back"/>Back</button>
above this line :
<div id="input-colour-container" class="selected">
in index.html

Hi. I haven't had a chance to check back yet but I think more than adding the button, this issue is more about resetting state, e.g. the variables set based on the options you choose at the beginning.

I won't be able to really work on this again until after Easter, but I can always spare a few minutes to check a pull request if you/anyone would like to make one! :)
