how it handles "advanced" pkgspecs for the state= cases

on the command line

Various additions to make sure timed out and failed hosts are taken out of the playbook even if failed
during setup, async tasks, or poll operations.  This introduced some redundancy so I've made some
notes in the code where things need to be refactored to remove them.

Annotate more files, fix missing imports messing with playbooks.  Hey Tim, please test your stuff :)

modify build/spec file to work on el6 with quasi-broken setup process

Die gracefully...

remove data_files section from setup.py for some reason or another

Generic AnsibleError exception + host inventory missing exception.
First shot at catching these in a generic way in bin/ansible*.

What we are running is actually a "play" (multiple plays per playbook) so rename the function to make it more clear

but this is more or less a mirror of what /bin/ansible does.  It also has a 'fire and
forget' mode if the poll interval is left off or set to 0.

yum module

add state=latest and clean up the output cases
added some fixmes on verification

happens only on needed hosts, allowing some hosts to fail and drop out of the running.

is not letting async_wrapper daemonize itself when it does work fine when directly executed.

Updates for better RPM packaging (plus tasks)

Spec file installs default example hosts files
Spec file marks the contents of /etc/ansible as %config(noreplace)

Example hosts file now with instructional comments

Fixup distutils: setup.py

Clean old cruft: section 5 man pages

touch up to yum module.

fix a couple of bugs
comment about state='latest'

Add manpage for ansible-playbook, since it is a command.  More detailed docs will remain on the web site.
