css & meta data clean up

style.css
remove some redundant css ( e.g. there were two .pagination>a declarations)

alphabetize css cause it's easier to read that way :)

change h2 selector to .date

index.php
combine google font calls into a single call
add .date to h2 that pulls in the date
remove type="text/css" as it's not needed in html doctype.
Added <!doctype html>
