0.9 release

[Libor Polčák]

Hello,

I released 0.9 containing a smaller set of changes compared to latest "major" 
versions but the paper uncovered an inconsistency in access to unwrapped APIs:

* Firefox: deactivate window.name wrapper for Firefox; Firefox provides 
protection since 88 and
        JShelter wrapper brakes pages
* Enable webworker wrappers by default, see the paper 
https://arxiv.org/abs/2204.01392, §4.3
* Tidy up popup UI and FPD report UI
* Show wrapper groups descriptions in options.html

Someone please update web.

Thanks

Libor
