Adding support for discarded and hidden tabs

[esanchma]

This PR enables context menu checkboxes for discarded and hidden tabs. To do so, it needs a couple of new permissions.

It also merges the 2 previous PRs.

@mikl This extension hasn't have any activity in 6 years. How do you feel about doing an update in AMO? If you don't want to do it, maybe I could change the id and upload it myself?

Hi there,

I’ve merged #1 and #2, and I’m working to make the extension work in Chrome-based browsers as well as Safari.

This change is a little more involved, and I’d like to wait until I have cross-browser compatibility working before adding additional complexity, hope you understand.

Looking at the Chrome Documentation, they have no filter option for hidden tabs: https://developer.chrome.com/docs/extensions/reference/tabs/#method-query – and giving unknown options causes errors, so we can’t easily add this filter if we want to keep cross-browser compatibility.

Yes, hidden tabs seem to be a firefox only thing. Maybe a check on typeof tabs.hide == "function" to do that only in firefox may make sense there. I'll try to rebase this PR over that

Alright, I’ll mark this MR as a draft for now.
