This state enables the official saltstack package repository in order to
always benefit from the latest version. This state currently only works on
Debian and Ubuntu, and aims to implement the installation recommendations
of the official documentation:

better newlines with iterations.

This will make the _defaults.conf file for master and minion
better by removing some empty lines in some code blocks

Updated gitfs jinja, to mirror master file

Gitfs for the minion is possible with salt 2014.7
Updated config _defaults.conf and pillar with example
Tested it on Archlinux with salt-call --local state.highstate

I don't understand why unnecessary ``-`` were added after and before ``{%-`` and ``-%}``

Fixes issue where a gitfs remote that has no child options would cause an
error. Also fix up bad yaml in pillar example.

Commit 2b51a6f0c3 introduced options for gitfs_remotes in a pillar by using a jinja test to see if a parameter is a mapping (dict etc.). This feature however is only available in jinja 2.6 or newer (see http://jinja.pocoo.org/docs/dev/templates/#mapping).
Although this version of Jinja is available on Ubuntu, other OS / package managers do provide older versions (2.2.1 in RedHat 6).

This change makes use of the "iterable" test which should do the exact same thing.

It doesn't seem to be available from pip anymore, and may not be
a real dependency. Salt-cloud certainly seems to work fine without
it.

This allows users to easily add configuration settings that the formula
doesn't yet provide, without having to modify the existing templates.

Fixes #48

Closes #45

Fixed an apparent typo in the autoreject_file setting (which was listed as autorejecte_file)
