Fixes typos.

Just a couple of minor spelling fixes. Sorry about the extra diff from trailing whitespace removed-on-save by Sublime.

On your resume, is there a reason you don't link to the linkable bits? I noticed it first on "Iconathon" since I wanted to know what that was, but some other things like "Summer of Code" and "CivicRush.com" (and/or CivChoice.com) might be worth linking? If you don't want to detract from your message, maybe you could style the links to look like body text but underline on hover?
