Do not store in browsing history hash changes

[dascritch]

Should we not storing URL hash changes in chapters or make it optional ?
The main issue is that when you're using chapters, we're natively making a lot of history entries.

Trying to resolve that may be problematic as we will recreate the wheel. May be using the History API but we may have a situation, or it may be retired because of security issues, which is understandable.
