Don't set PasswordAuthentication=no here because the connection plugin will do that unless a password is actually specified with -k/--ask-pass.

	nocows = 1 in ansible.cfg
	or old environment variable ANSIBLE_NOCOWS=1
add to ansible.cfg example

Moved *jina* to *jinja2*

Jinja extensions adds features to the jinja2 templating engine. This
patch allows module loading for the templating engine vian an
ansible.cfg configuration key (jinja_extensions).
The default behaviour doesn't change (no module loading).
Requested modules can be added coma separated in ansible.cfg

Adds whitespace handling in jinja_extension config

Added whitespace handling in jinja_extension configuration directive, so
things stay safe if user adds spaces around comas in the directives
list.

Adds config example for jinja_extensions

Added config example with multiple extentions for jinja_extensions

Default to -H to set $HOME appropriately.

Hash variables are currently overriden if they are redefined. This
doesn't let the user refine hash entries or overriding selected keys,
which can, for some, be a desirable feature.
This patch let the user force hash merging by setting the
hash_behaviour value to "merge" (without the quotes) in ansible.cfg

However, by default, ansible behaves like it always did and if any value
besides "merge" is used ("replace" is suggested in the example ansible.cfg
file), it will also behave as always.

Added a boolean constant scp_if_ssh to the config
Added scp support for the ssh connection plugin
Refers to #1279

The config file incorrectly mentions the --private-key-file flag.
Should be --private-key

If PasswordAuthentication is enabled (which is the default) ansible 
will spawn (multiple) ssh's with a password-prompt which corrupts 
the terminal, and cannot be properly used.

So it is better to not allow for password-based authentication using 
-c ssh. The result is that authentication fails but Ansible 
continues to work

The global config file is loaded from /etc/ansible, not /etc
