Only trigger anchor scroll if hash is present in url

Mainly so scroll position can be preserved after a refresh without hash
Trimmed education headers line height

Looks better with headers spanning more than one line
Added thesis description and tweaked education display
Replaced toggle plus/minus icons with chevrons

Didn't want to include another full icon font, so I made a stripped down build (http://icomoon.io/app) of Font Awesome containing only the chevrons
Replaced chevrons with angles for a lighter look
Added extended descriptions to experiences
