Properly track the dependencies for steps.pl.

This finally correctly tracks all of the files steps.pl (the file that
generates tutorial.h) opens and reads for both the tutorial programs
and the code gallery.

+# First collect the various files this all depends on. This
+# is simpler for the tutorials since the directory names
+# are structured. For the code gallery, we have already
+# determined the list of names of the relevant subdirectories
+# (which may be empty), so we can create the list of files
+# the following target depends on without a GLOB and instead
+# using just a FOREACH loop.
+#
+# For tutorial programs, the steps.pl script will read
+# tooltip, kind, and builds-on files. For the code gallery
+# programs, the 'kind' is obvious and we only need the other
+# two categories.
