moved css into file, fixed html spacing, got better js link for jquery

Basically did some cleaning up and light web best-practice stuff. 

I couldn't remember the link for the live site, but I seem to remember better styling on it that I couldn't reproduce locally. But, the version at alexschiff.github.io/personify looks just like mine, so I bet you have a non-current version on github (in which case you should merge this, then yours).
