.label without .label-* is invisible

Thanks for this excellent framework!

One problem though. Form labels started showing up as white text on white background on a 3rd-party web app. The issue is that the labels have the class "label", not "label-default/warning/whatever".

bootstrap.css defines "color" only in .label & then specifies only the background in .label-default, so if .label-default isn't called, only the font color is changed!

Although its more verbose, the best way to fix this is to define @label-color & @label-link-hover-color in each of the .label-xxxx sections and to define @text-color & @link-color in .label so that doesn't remain a problem if there's any older subordinate bootstrap.css CDN files involved.
