Fix project template

Currently, a page like http://openhatch.org/projects/OpenHatch looks like this: http://i.share.pho.to/afcb9543_o.png

I did a bit of digging and found it this layout issue is caused by a missing closing tag which messes up the DOM.

That pull request has two commits:

* The first one fixes the indentation to make it easier to find unbalanced tags (only leading whitespace is changed)
* The second actually fixes the issue by adding the missing `</div>` (it also removed an unneeded `</span>`).
