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

If ANSIBLE_KEEP_REMOTE_FILES=1 is set as an environment file, remote files will not be deleted, which is useful only for development debugging purposes.

Move setup.py stuff back to top level as "make sdist" was not working, plus, it makes sources cleaner.

Distutils MANIFEST.in, setup.py -> packaging/distutils/ directory.

Because folks on RHEL 6 (not CentOS 6) have some issues with asciidoc, do not build the asciidoc from
the rpm or make install targets.  Also modify the make install (only) to copy over files into the library
directory since the setup.py does not do this (due to a distutils bug, more or less).

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

Fixup distutils: setup.py

Clean old cruft: section 5 man pages

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

Drop other man(5) pages so we can have only one source of docs -- ansible.github.com for those operations.
Easier to maintain and much more verbose.

service module is installed by setup.py

and treeish saving everywhere.

there are probably some quirks here we'll want to refine further later, for instance, we should
be able to do nicer things with "can't contact host tracebacks".
