Thorben Kroeger e91e1a742c Theming: fix disabled menu items in dark theme 
In the dark theme (fusion style under linux), disabled
menu items looked bad due to (1) SH_EtchDisabledText being enabled
and (2) a bright color for the etch effect.

This patch adds color values for normal and disabled text colors
for menu items. It also adds a color value "style" which indicates
that the color should just stay at the default of the style.
The default theme uses this value for the new menu item colors,
while the dark theme fixes the ugly colors.
The patch also disables etching for disabled text.
