Title: Microdata implementation in the CMS with the use of plg_system_microdata and JMicrodata

DO NOT MERGE YET
----------------------------
First everything needs to be tested and discussed!
This is a working demo. It also includes the ```plg_system_microdata``` plugin https://github.com/joomla/joomla-cms/pull/4118 pull request.

HOW TO TEST
--------------------
First I recommend reading this article http://magazine.joomla.org/issues/issue-aug-2014/item/2233-rich-snippets-structured-data-microdata-rdfa-isnt-so-simple

Also make sure you have the ```plg_content_vote``` and ```plg_system_microdata``` both enabled.

You will also need this tool provided by google to test the markup and the SERP (Search Engine Result Page) preview https://www.google.com/webmasters/tools/richsnippets

Step by step
---------------
1. Go in the Administration area, then from the top menu select: _Content → Article Manager_
2. Now select and press _Edit_ on any article you want
3. From the option tab select: _Publishing_ ![administration - article manager edit article](https://cloud.githubusercontent.com/assets/1648497/4260976/317a139a-3b58-11e4-9a68-28f3ebe98eab.png)
