Not using colored background for added and removed lines is a missed
opportunity to make diff lines easier to grasp visually.

Use a subtle red/green background by default. Make the font slightly darker
to improve contrast.

The variable diffcolors seems like a fitting place for the two new colors.
However, adding them to that list causes problems if diffcolors saved in
.gitk then contains three instead of five colors. This could be solved by
modifying the variable after loading .gitk. I'm not sure if that would be
the preferred approach or where to implement a special case like that. To
avoid the problem, I introduced a new variable diffbgcolors.

I've been using gitk with this patch for a while, and I find the new
appearance *very* pleasing! It gives gitk a fresh, modern look.

There is one major gripe, though: the new background color overrides the
selection background and makes the selection invisible. This is a
showstopper.

Note that the search result highlight does not become invisible.
