function name_element_pre_render in Name Field 6

Same name and namespace in other branches

1. 8 name.module \name_element_pre_render()
2. 7 name.module \name_element_pre_render()

This function forces the error class attribute onto each of the empty element components as required, themes the element and controls the title display.

TODO: There is a lot of WTF here. Why does this need such a hack to propagate the error class down? Is the error element name wrong??
