[Feature request] add bookmarks export

[lucekp]

Possibility to export bookmarks/bookmarks category with items. Use case: easy sharing of bookmarks with other people not on my network. Easy transition to/from flame -> Support of browsers format would be nice :)

I second this request. It would also be nice for backups as it takes time to create a nice dashboard. In case of any unexpected container issues, backups would accelerate the setup process.
