This reverts commit 6f1a58ab.

The NOSETESTS variable can be used to support customizing the nosetests
parameters.  This allows providing custom nose parameters such as
--with-coverage.

build manpages.

If someone try to run the test suit with ansible already installed,
the mix between content in /usr/share and in the git checkout
can result in strange failure ( as I found out the hard way ). For example,
the test_copy module will call the action plugin for copy from git,
who will call the 'file' module from system, passing unsupported arguments

- use egrep patterns to detect BSDs in one ifeq
- use seconds-since-epoch as input for BSD date (-r option)
- get seconds-since-epoch from git log with "%at" format string

this is to make use python2 when nosetests points to python3:

make NOSETEST=nosetests-2.7 tests

Only the nosetests aren't using the PYTHON variable now.

No reason to build the website for RPMs/DEBs, adding dependency on
Sphinx.

This commit makes the Makefile nicer for packagers so they can select versions
of python. E.g. on a RHEL5 system with Python2.6 (installed from EPEL)

	make PYTHON=python2.6 install

Adding a script to auto-generate an authors file, runnable from 'make authors', which is called from 'make docs/webdocs'.

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

Without this, module_formatter.py relies on the installed ansible which is wrong in more than one way.

On RHEL5 and RHEL6 there is not argparse, and 'make rpm' fails because of this.
With this change it works, and I can test and fix my own documentation...

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

So they can be shared/compared by people in different timezones
