Add custom friendly URLs

[shaal]

Custom boards get (unreadable) URLs, ie:
https://contribkanban.com/node-board/91839946-8af5-45b0-822b-35b4375743f0

Instead, I would like to have friendly URLs.
Maybe prefix them with the board owner's username to avoid duplicates, and then the machine name of the board title?
ie:
https://contribkanban.com/boards/shaal/ootb_8_8_roadmap

So, there's a few problems with this, at the moment:

• Usernames are emails, so it'd be /boards/myemail@example.com/machine_name which can be problematic.
• It could just allow machine names and provide conflict detection.

The new interface could support linking as /node-board/:uuid for backwards compatibility and implement a new route called /collection/{machineName}.
