Formatting of the projects on the Event pages

[khoeger]

The formatting of the projects listed on the event pages is strange. See April 2014's hackathon page for an example.

Proposed solutions

• Take out a new pull request
• Style 'Projects from this event' in the same way as all the other headings (such as 'When', 'Where', etc.)
• Make the project titles smaller (I think they should be smaller than the section title 'Projects from this event')

Thoughts?
