About page volunteer listing bug

[JohnLZeller]

The php that generates the array used to build the html sections for the volunteers about section has a bug. Revision 9ba9569 gives a temporary fix, but we need something permanent.

The array bug causes the first element of the $output array to include all volunteers, which has the effect of the first section displaying everyone with no section name, followed by the properly formatted sections.

A pretty printed version of the array that is generated is here: http://pastebin.com/1ywpz1yL
