Fix up homepage ready to announce the winners

[rossbruniges]

Using this bug to track feedback on the homepage updates - what data we want, what data we don't want. Please include copy updates for the page here too.

Top bit of the page

• have removed the right most section in the bit under the headline so that we're no longer saying that we're announcing winners - as they have been announced!

Middle bit of the page

• Removed the random 5 entries and replaced with a 2 x 2 grid of winners containing - project name, project thumbnail, project brief description and project team info
• Blog and events to the side of the winners

Questions:

• Do we want the thumbnail? Not sure how much value they're bringing, and not all winners have a thumbnail
• Do we have better project team information we can include - Will, do you have better names? Equally, is it important?

Bottom part of the page

Have included the category links so that people can still browse all the ideas
