- Add a hotkey ("c") for the capture action.

- 'org-protocol://capture' supported alongside the already supported 'org-protocol://store-link' pseudo-URL
- org-capture can capture the text selected on the page (this is the only purpose of the new "Access your data for all websites" permission)

- Add GNU Emacs icon to the popup

- Add a hotkey (Ctrl+Alt+E by default, "E" for "Emacs")

- Use a popup with a preview instead of immediately storing the page.
