Adds color to the prompts and output of git-add--interactive.
-Reads config color.interactive, respects "auto", "true",
"always", and anything else.
-Uses the library Term::ANSIColor, which is included with modern
versions of perl. This is optional, and should not need to be
present if color.interactive is not on.
-Reads color.interactive.<slot>, where slot is "header", "prompt",
or "help", colorizing output accordingly.
Documentation/config.txt is updated to reflect the new keys.
I cannot test this or see how it looks in manpages, however,
as I cannot install the documentation build tools.
Unfortunately, I think the default colors are ugly, but all colors that
are readable on both black and white backgrounds are probably ugly.
This patch does not colorize the diffs, because that is a larger
job, and very distinct from this (simple) task.

gzipped patch is also attached, just in case.
