Removed incorrect scroll bar, logical fixes.

Changed span12 to span11 in the project tabs, as this removes the
horizontal scroll bar.  Not the best fix, as it limits space slightly,
but I can't find what is causing the space to the left of the tab content.

Also changed ordering of fundraisers to be based on start date rather than
end date, to handle the case of a fundraiser that was ended early, and a
new fundraiser being created that ends before the old one would have ended.
Merge branch HTML spacing and scroll bar removal

The added whitespace messed with the changes of span12->span11.
