started the concept_02 folder

the intention is to use concept_02 to mock up the visuals and have it
become the site once its working. I made the concepts 2 folder to keep
things tidier while still having the old css and images available one
folder up.

-the sprited hover effect is working correctly
-!? I have no idea why an extra <a> tag turns up when i run the site,
consequently contacts appears twice.
