Safari support: every host permission is reported as "additional"

[fregante]

This appears to be the case from initial trials. Further testing needed.

Figured it out: Safari’s permissions are stored as *://*.github.com/*, which might not be a direct match with what's in the permissions key

[fregante]

Technically the current situation is correct. *://*.github.com/* is different from *://github.com/* so it is, in fact, an "additional" permission.

The correct solution is to change the manifest.json permission to what Safari gives access to, but I'm afraid that it will trigger a warning in Chrome.

Testing needed

Edit: testing is hard, but I'm confident that prepending *. to the host is a substantial change.

I’ll implement loose host matching with an option, so only the domain is considered when comparing permissions and nothing else.
