main/st: please include the Xresources patch!
As stated on the ML, this little terminal is always grey-on-black, like
the framebuffer is.
With a very small patch from suckless.org the .Xdefaults can be used to adjust that.
With an additional patch of mine, the respective properties .background etc. work as expected (color array indexes adjusted).
