#6 Changes the -sh coloring

[Rainer Mager]

(patched against 0.4.0)

I didn't like the way shading worked. Basically I
wanted the ability to smoothly brighten or darken the
background so that it always looks good. I changed -sh
to work like this:

-100 to 0 : darken from pure black to no adjustment
0 to 100 : ligten from no adjustment to pure white

I hacked this in and it works for me. It may have
broken fading but I'm not sure they were compatible
before. It may be slow and hasn't been optimized at
all.

I now use this in .Xdefaults with my font being black:

Aterm*shading: 60
Aterm*tintingType: true
Aterm*tinting: #ffffff
Aterm*transparent: true
Aterm*transpscrollbar: true
