Fix for bug 32220 (checksetup.pl gives bad permissions). Majority of

patch submitted by seth@cs.brandeis.edu (Seth Landsman).  checksetup.pl
now no longer twiddles the permissions of the contrib folder, and
properly sets the permissions on the folders inside the data folder.

+# This abstracts out what files are executable and what ones are not.  It makes
+# for slightly neater code and lets us do things like determine exactly which
+# files are executable and which ones are not.
+#
+# Not all directories have permissions changed on them.  i.e., changing ./CVS
+# to be 0640 is bad.
+#
+# Fixed bug in chmod invokation.  chmod (at least on my linux box running perl
+# 5.005 needs a valid first argument, not 0.
