New Emoji Picker for Posts

[metaspartan]

This adds in a new Emoji icon next to embeds and images for posting, which brings up a nice selector to select an emoji, it can go off system themes only (light or dark) but we could expand this eventually...Seems to work great on mobile as well, this uses unicode emojis so they fit right into your current message.

This does have a new dependency required npm install @joeattardi/emoji-button so you will need to do a fresh npm install of the frontend for this to work, otherwise should be good to go @lazynina @maebeam @diamondhands0

See feedback comments please. Also, this may take a while as there are dependencies to be audited for vulnerabilities.

@carsenk I suggested some changes that should apply the selected theme to the emoji picker. This is an example of what it looks like on legends theme with the suggested changes

@maebeam for 2nd review. I looked through the dependencies of the emoji-button lib and they appear to be well-maintained and safe from my review.

While this PR looks great, our package-lock.json file is currently frozen until we implement LavaMoat to protect against dependency tree compromises.

How do you want us to proceed? package-lock.json should be in gitignore?

A suggestion would be to fork all deps into bitclouts own repos and then link the package.json to those, requiring approval for upstream changes, etc.
