Add font families alternatives
Add a page that lists the news posted by a user.
Refactor event handlers for voting news and comments.
Add missing event handlers for voting the main comment in the comment page.
Remove 'apisecret' from the parameters for the voting event handlers.

The apisecret variable lives in the global scope, so there is no actual need to
pass it around as an argument.
Implement a more generalized event handler for voting news and comments.
Add an optional callback parameter that is called after voting an item.
Generalize the procedure to attach voting handlers to the selected elements.
Remove double escaping
Better handling of deleted news in permalink pages.
Make rendering more like that of deleted comments.  That is, don't show
author details and don't allow new comments with deleted news as parent.
Other titles have "News" in lower case.  We should be consistent.
Missing '+' means latest news page has no h2 title.
Avoid redundant user lookup but refactoring update_auth_token api.

Both calls to update_auth_token had argument '$user["id"]' and the
first thing update_auth_token does is looks up the user record.
Change update_auth_token api to take the user record instead.
