nodm: new package

[Peter: propagate linux-pam dependencies/comment,
	needs wordexp.h, not available on uClibc,
	use /etc/default/nodm for config override,
	correct github/site/source handling,
	disable help2man]

+	help
+	  nodm is a minimal display manager that simply logs in
+	  as a given user and starts an X session, without asking
+	  for username or password.
+
+	  For those cases where automatic login is needed (and
+	  does not imply a security issue), nodm is simple to setup,
+	  lightweight, and it should do exactly the right thing.
