[rfe] change threadpane row text color for junk messages like Apple Mail this makes identifying junk messages in the thread pane much easier, instead of just relying on the junk icon column (which may be hidden). From http://www.mozilla.org/access/xul-guidelines "Don't rely on color alone to present information — for example, don't use different colored dots to indicate different states. Avoid low contrast cominations such as blue-green or other color combinations such as red-green that are troublesome for individuals with color-blindness (10% of men)." We should be OK, because we aren't using color alone, as we still have the junk icon column. I'm not sure how this would work with the current "Label" feature, to avoid conflict with any existing "Label" colors. I'll attach a screen shot of apple mail for comparison.
