Add support for anchor links

[TDesjardins]

Nalu uses anchors for routing. Therefore anchors couldn't be used for scrolling to a special element. Furthermore the content is loaded asynchronous which also prevents that.

The idea is to add an additonal info which contains the anchor info to the routing path which can be used to scroll to this element.
This link shows a guide how this could be done:

Before implementing this we should investigate if there are any best practices for adding this notations to the hash.
