URL bar refactor

[razvanlitianu]

Problems with the current implementation:

The URL bar is a core part of the application, many parts interact with it. Over the time the codebase grew and we don’t have a single coherent way to interact with it. It has and implements many delegates.

Some properties which should be private are exposed as public.

Possible solution

Reimplement the URL Bar component, extract it to a separate module.
