Documentation Link

There is a link leading to the docs now. In the moment the folder is named "man1", but in the future, when there is a doc a simple change to "man"(which will be also included as a submodule) is enough.
Also, the logo will link to the root folder now(so to the homepage).

For the "man" repo is to say, that the markdown files will need a [frontmatter](http://jekyllrb.com/docs/frontmatter/).
