New layout for the Dreamboard page

Nitya is putting together "Dreamboard parties" right now. We invite a few friends over with their laptops, talk, laugh and build boards...fun! We noticed that working on a board when on a laptop is a bit of a trial. The gallery seems to be in the way alot of the time and more time is spent working on the board itself than looking at the gallery. So I've made some changes to the Dreamboard page: the gallery is now a slide-up/slide-down control so you can get rid of it really easily and we've moved the top links down to the bottom to give you more room to work. I've also fixed some problems with Image Search and Internet Explorer 7, so that should work perfectly now. As ever, let me know if there are any problems! I hope these changes will make things much easier for everyone.
