Inline mirror links (forwardlinks)

I propose to add the possibility for inline mirror links.
A forward link would be added as a child of the linking node.
Renaming a node would rename it everywhere

* Context
    * Path
        * inline ((dynamic bullet))
            # dynamic bullet
                * mirror content (or maybe no bullet)
            * Stuff about mirror linking...
        * ((dynamic bullet))
            * mirror content (or maybe no bullet)
* Another Context
    * Path
        * ((dynamic bullet))
            * mirror content (or maybe no bullet)
