Subject: [PATCH perfbook] utilities/autodate.sh: Make newer tcolorbox behave as before
tcolorbox 4.40 or later has wider skips around its boxes by default.
Putting \tcbsetforeverylayer{autoparskip} in preamble restores the
previous default behavior [1].
It needs to be put conditionally because the command changes older
tcolorbox's behavior.
We use a lot of booleans for conditional things in perfbook, but
their values are changed based on targets such as -1c, -nq, -qq, etc.
However, version of tcolorbox is common to all the targets.
We need a different way to put the \tcbsetforeverylayer{} command.
As autodate.tex is included in the preamble of perfbook, we can do
this by adding some script in autodate.sh, which will generate the
command when a newer tcolorbox is found.
Also update Makefile to let autodate.tex depend on autodate.sh.

Hi Paul,
I have kept this one on hold for a couple of weeks.
perfbook can be built without this change, but the wider skips
around Quick Quizzes looked waste of space for me.
This change actually restores the exact behavior of older tcolorbox.
Thanks, Akira
