first_found lookup_plugin - replaces first_available_file
- useful in tasks/playbook inclusion
- task-specific inclusion

allows searching paths and files
check if the term is a dict so we can take a simple list of files (like first_available_file) takes
add (un)silence_nagios and command actions to the nagios module
also fix a typo with the check_mode check
Added a use_proxy option to get_url.
Start of more OSX facts for setup

Added a Darwin family, commit acc1c004 had added some network facts
but weren't being shown as the Darwin family wasn't in use. This commit
reveals these facts.

A Darwin(Hardware) class has also been created ready to be populated with
hardware facts.
Teach makefile to accept different versions of python

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
Added a fail_on_missing option to fetch.
Clarified that proxy can be changed via an variable.
fixed typos
Add openbsd_pkg: package management for OpenBSD.

* Code influenced by the service module but without classes.
* Thanks to @dhozac for input and review.
* Thanks to @johanwiren for getting me to push this out the door.
Teach setup about OpenBSD package manager.

* We cannot depend on the path because FreeBSD for example uses the same path.
Add socket timeout to uri module.

The uri module can be configured to abort after a specified timeout if
it cannot connect to the configured uri. This prevents a uri action from
hanging indefinitely when the remote endpoint cannot be reached because
it is unavailable, there is a firewall in place etc. The default behavior
is left unchanged: timeout=None

This change also introduces a new type for module_parameters: int
Code was added to perform conversion from string -> int type in
module_common.py.

The new type was required in order to play nice with httplib2 which
refuses to accept (and convert) anything other than a numeric type for
the timeout value.
file module should check invalid arguments (fixes #2135)
should always download when force is set
Allow 'make rpm' without the need for env-setup

As it used to be before, 'make rpm' from a cloned repository should work without the need to run hacking/env-setup. It's an easy fix, in line with what we already did for the man-pages.
Update playbooks2.rst

Added doc on encrypt capability of vars_prompt.
Assuming the example in https://github.com/ansible/ansible/blob/devel/examples/playbooks/prompts.yml is still valid.
Adds crypt scheme list for vars_prompt

Added more details on encrypt usage for vars_prompt, including a list of
crypt schemes and a ling to the passlib documentation.
Cosmetic fixes

Fixed typo in passlib URL link
Fixed style in cryp scheme list
Fixed bullet 7 in variable precedence section
Adds statement regarding passlib requirement
Update the Makefile and build-site.py to notify of missing dependencies for doc compiling
Fix example crypt to include trailing $

Fixes #2305.
