Use -moz-menubartext rather than MenuText for text on menubar styled elements
Design have changed our dark theme in Ubuntu to have light coloured menu popups with dark text (rather than dark popups with light text, like we had previously). Unfortunately, this exposes a bug in the Thunderbird theme, which styles the tabs in the main window and the toolbars in the compose / addressbook windows with the background of the menubar (which is dark), and the text colour of the menu popups (which used to be light, but is now dark).
It seems that Thunderbird should be using -moz-menubartext rather than MenuText in these cases (Firefox seems to do this already, so it didn't break with our theme change)
