page.

check path is directory
added manpage & setup
small cleanup
shut up module_formatter in utils to avoid trace print on crud files in library

- added the ANSIBLE_CONFIG environment variable

Library functions and modules should be in the 3 man page section. Also the files should end in '.3'

Add a basic ansible-pull man page.

Add the example playbooks/scripts to the RPM package.

Closes #841

Remove the -D module debug flag, which no longer is functional due to sudo pty requirements, and replace with -v/--verbose.

This flag will show playbook output from non-failing commands.  -v is also added to /usr/bin/ansible, but not  yet used.

I also gutted some internals code dealing with 'invocations' which allowed the callback to know what module invoked
it.  This is not something 0.5 does or needed, so callbacks have been simplified.

treated -D as a way to show stderr, and make sure modules don't include things on stderr.
Update docs and test module script to come into line.

ansible-playbook release-my-app.yml --extra-vars="version=123"

And make $version available in the playbook without re-editing the file

Change manpages to build from *.in and add comments about how the make
targets work.
