03bdf82c broke the header fonts in IE/FF.
IE/FF does not inherit the base font for headings, which makes all headings in IE "Times New Roman".
This change explicitly sets @headingsFontFamily to make sure all browser use the proper font.
Here is a build of the latest 2.0.2-wip docs: http://pelme.se/~andreas/private/bootstrap_docs/
Open in IE or Firefox and notice how the headers are in Times New Roman. (Also note that the font-weight changed to be non-bold, is that intentional?)
