Add share button to submenu

[sevmonster]

Unless I'm missing something, there's no way to share the currently selected folder. I find this very inconvenient, especially that you can't share the toplevel folder without editing the database to point an existing link/insert a new link pointing to it.

No clue if this works, since when trying to make a test build, npm run build crashes for some reason:

% make build_frontend
make: *** [Makefile:10: build_frontend] Illegal instruction (core dumped)

% npm run build

> [email protected] build
> webpack

[1]    206949 illegal hardware instruction (core dumped)  npm run build

I have AVX512 disabled to fix an issue on my system so maybe that's it.

I know you prefer IRC to discuss changes, but I was curious and it seemed easy enough. Plus I'm not an IRC guy.
