Add first initial implementation of Emoji search in address bar

[rugk]

(called omnibar)

Edit: Fixes #33

Blocked (?) by:

Upstream declined change, but in the future a whole new API could come.

That means, for now, we could only adjust this to copy the emoji to the clipboard, at least. (after we get clipboardWrite permission)

[rugk]

TODO:

• add options (opt-in) for emoji bar search
• request clipboardWrite permission when enabled
• make logic independent from other settings in add-on (EmojiInteraction)
• (optional) search for emoji on emojipedia instead of copying it

Ready to merge.

Possibly only TODO:

• split PermissionRequest module out of this. It's actually quite nice.

Note: If a solution for opening the popup or so is found, passing the search term to the popup should be quite easily possible: missive/emoji-mart#266 (comment)
