Properly template list of hosts in playbooks.

In playbooks, hosts can be a YAML list. We templated the list before
converting it to a semicolon-separated string, which actually templated its
repr. This converts to a string first. A basic unit test is included.

Renamed module, fixed idempotency, removed debug param.

Fix for get_selinux_facts

Fix to make 0.5 hosts with failures not be included in future task executions

get_hosts() was treating [] (meaning complete restriction, no hosts allowed)
the same as None (meaning no restriction, all hosts allowed). Fixed logic.

This switches to using selinux library calls instead of parsing the
output of sestatus.  This fixes issue #428 where the output was slightly
different than expected on F17.  Tested against debian (non-selinux),
centos5, centos6, and fedora17.

Test for play.vars_files == None, avoiding nasty traceback.

Avoid traceback when vars file has no vars items. Could warn or fail instead.

Playbook test for no vars_files with len(), but that excepts if play.vars_files==None, as can happen when there's a vars_files section with no vars files listed. What is the ansible way: ignore, warn, or fail with message (instead of traceback)?

Listed python sub-packages in setup.py.

Removed line that caused stacktrace

Allow "=" in k-v values.

template path for handlers: include

Fetch module: run dwim on dest after templating, not before

Feature: Add state=reloaded

updated connection.py to have the same interface for exec_command on both LocalConnection and ParamikoConnection classes
