Add user's comments to user profile page
Merge pull request #196 from josephwegner/master

Make dev setup and startup easier
send an error message instead of crashing when a user does not exist
fix user pages that do exist, and refactor how comments are fetched
refactor adding comments to news items into a single function
create a convience function to add comments and votes at one time, and use that for both userNews and index. Also make sortByScore a pure sorting function so that what it actually does is clearer.
clean up after rebasing from master
refactor news item querying to add comment counts and votes to every query
