Tweak formatting.

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

Solving bug : sysctl check_after failing on multi-value sysctl parameters

Add NetBSD support for 'service' module, and add an example to 'lineinfile'

Now handle positive integer value in virtual files if they are separated
by group of space characters where the count is unpredictable.

Documentation fix for apt module: install-recommends

visible on line 121

A collegue of mine has added basix AIX support to the setup, user and group modules.

a colon, which needs some special attention.

See github issue 2702

Add example of read-write git checkout via ssh
