Fixed explanations, and improved logic code to client_acl

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.

Reference about this config value: http://docs.saltstack.com/en/latest/ref/configuration/master.html#yaml-utf8

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

Fixes #48

See #37 "Fixed file_roots config generation with several environment"

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

made fileserver_backend and gitfs_remotes look more like expected

Moved package_table to it's own file, imported by sls files
Moved minion package under watch
Fixed some template mistakes I made
