Context menu support

[clmay]

As a user, I want to be able to use the context (right-click) menu to take a snapshot of the current page.

I will try to find time to dig into Codetour.md to see how the extension works.

If anyone has thoughts on how to implement this, please let me know. I don't suspect it should be hard to add. Just have to see how the WebExtension API registers context menu items, I would think.

Sure. Perhaps look at how it’s done in e.g. src/main/background/snapshot-tab.js.

Would be even better if we could just replace the “Save Page As...” implementation..

@clmay did you manage to work this out?

You know, I haven't followed up on this, bought a fixer-upper a couple months ago. I'd like to, but for now project time is scarce.
