[PATCH] Use color.ui variable in scripts too

[Matthias Kestenholz <mk@spinlock.ch>]

	This patch adds color.ui support for scripts. It does that by
	modifying `git config --get-colorbool`, because there is no
	way to differentiate between undefined and `false` configuration
	variables in scripts. Additionally, the scripts don't need to be
	changed. I have only tested git add -i; git svn uses the same
	functions in Git.pm, so it should work too.

	Of course, it would have been nicer if I had made this change
	before the release of 1.5.5. The 1.5.5 announcement reminded
	me, that this had yet to be done.
