Merge pull request #1 from Kollode/master

Working Plugin include and reworked handling of the site package.
[NEW] Added an Abstract MdViewHelper in order to have different MD implementations

Namely Md and MdExtra from the used library. MdExtra is currently not available thou.
[NEW] Adds some default responsive template from http://www.initializr.com/
[NEW] Adds basic structure for documentation

Which actually uses the package for rendering
[FIX] Removes obsolete images and moves others to new places
[NEW] Adds a new option "addRoot" to menu view helper

This option will add the root of the menu (or in other words it's starting point) on top of the resulting pages structure.
So if you have something link

page1
	page 1.1
	page 1.2

And you start your menu at "page1" the result page list will look like [page1, page1.1, page1.2] if the option "addRoot" is set. If not, "page1" would not be part of the result.
[NEW] Some tweaks to the documentation

There is no actual content yet. :-/
