Update Modulefile, README, CHANGELOG for stdlib-4.0.0
Update function documentation for 4.0.0

Without this patch the function documentation is out of sync with the
functions contained in the standard library.  This commit updates the
functions.  I generated the list using this sequence:

    cd ~/src/puppet
    git checkout 3.1.1
    bundle exec puppet doc -r function > /tmp/puppet_functions.txt
    cd ~/src/stdlib
    bundle exec puppet doc -r function > /tmp/stdlib_functions.txt
    diff -U2 puppet_functions.txt stdlib_functions.txt | grep '^+' | perl -ple 's/^\+//' > functions.txt

I then replaced the README function documentation with the contents of
functions.txt which contains only the functions contained in stdlib.

  Update Modulefile, README, CHANGELOG for stdlib-4.0.0
Fix README function documentation

Without this patch some core puppet functions leaked into the
documentation for the functions contained in stdlib.  This patch removes
them and cleans up some of the formatting.

Make the anchor type propagate refresh events

Without this patch the anchor resource does not propogate refresh
events, making it difficult to subscribe to a class which has been
notified by another resource.
Add behavior example for anchor refresh propagation

Without this patch we don't have a spec test to make sure the anchor
resource type passes notify events along.  This patch addresses the
problem by using RSpec Puppet to build a catalog, apply the catalog,
then pull a resource out of the transaction and make sure the resource
was triggered.
