mod_http_xep227: Handle nil/errors opening archive stores This matches how mod_mam opens archive stores. nil can be returned when there is no data in the store yet (it doesn't exist).

mod_http_xep227: Don't require admin privileges to use import/export These APIs always operate on the current user account only. In the future we may want to have a more specific permission check though.

mod_http_xep227: Initialize XEP-0227 XML mod_storage_xep0227 only writes if there is XML already for a user (it uses the presence of an existing <user> element as an indicator that an account exists, although technically this is not something Prosody itself does, so it's a little weird).

mod_http_xep227: Fix validation of resulting export XML

mod_http_xep227: Fix luacheck warnings

mod_bookmarks2: Skip send_last_published_item (unavailable in 0.11) (thanks carlos) Not the most important setting, we can live without it for now.

mod_http_xep227: New module providing HTTP API for account data import/export

mod_default_bookmarks: Silence warning when probing for mod_bookmarks version

mod_groups_muc_bookmarks: restore bookmark injection on empty store

mod_groups_muc_bookmarks: fix typo/leftover from refactor The update_bookmark function no longer takes a "current" argument; passing it causes havoc in service:publish (because it gets the room JID instaed of the item as item).
