Make use of LocalConnection explicit

Add selinux support to file module - issue #46

Merge the SortedOptParser bits and debug attribute commits into
localconnection.

Conflicts:
	bin/ansible
	lib/ansible/playbook.py
	lib/ansible/runner.py
	lib/ansible/utils.py

This adds the options: seuser, serole, setype, and serange to the file
module.  If the python selinux module doesn't exist, this will set
HAVE_SELINUX to False and punt in the related modules.

This takes the options the user provides and applies those to the
default selinux context as provided from matchpathcon().  If there is no
default context, this uses the value from the current context.  This
implies that if you set the setype and later remove it, the file module
will rever the setype to the default if available.

Simplify playbook tests so things are not timing dependent in the poll section, which is leading to tests
not being consistent between runs, even though there wasn't an error.  Now we'll just check the final change
counts, which should be just as solid and lead to less churn in the events file.

Some minor code shortening.  Added a test to TestRunner.

Fetch Module

This adds transport variable to playbook.py.  It can be set with
'connection' in the playbook file.

Update test file -- we probably should not include the poll as the number of polls is changing between test
runs (that's ok, it's not intended to be realtime accurate)

Conflicts:
	bin/ansible
	bin/ansible-playbook
	lib/ansible/utils.py

Allow variables coming in from the playbook and the API to be expressed as dictionaries throughout their full life cycle
such that nested data can be made available in templates and playbooks.

Raise exception if effective uid of process is not the same as
remote_user.

This also uses self.transport when instantiating Connection object.

Adds support to specify connection type to use.  The option -c,
--connection is added when connect_opts is set to True.  connect_opts is
added to make_parser() and base_parser_options().

DEFAULT_TRANSPORT is set to paramiko.  DEFAULT_TRANSPORT_OPTS is a list
of possible transport options; it is set to local and paramiko.

Connection.connect() now requires that, in order to use LocalConnection,
you specify transport is local and that the hostname is localhost.

interface.

add very small subclass of OptionParser to sort the options so mdehaan is happy

Added usage info to bin/ansible-playbook, now shows options on bare command line. NOTE: bin/ansible outputs usage to stdout, bin/ansible-playbook to stderr. Should they be consistent?

that commands now trigger change events.

Add LocalConnection class to connection.py

This creates a LocalConnection class for the case when operating on the
localhost.  If the host, argument to Connection.connect(), matches
127.0.0.1, localhost, or the name of the host as returned by
os.uname()[1], Connection.connect() will opt to use LocalConnection
instead of ParamikoConnection.  LocalConnection implements connect(),
exec_command(), put_file(), and close().
