plugin XEP-0447: handle attachment and download: - plugin XEP-0447 can now be used in message attachments and to retrieve an attachment - plugin attach: `attachment` being processed is added to `extra` so the handler can inspect it - plugin attach: `size` is added to attachment - plugin download: a whole attachment dict is now used in `download` and `file_download`/`file_download_complete`. `download_uri` can be used as a shortcut when just a URI is used. In addition to URI scheme handler, whole attachment handlers can now be registered with `register_download_handler` - plugin XEP-0363: `file_http_upload` `XEP-0363_upload_size` triggers have been renamed to `XEP-0363_upload_pre_slot` and is now using a dict with arguments, allowing for the size but also the filename to be modified, which is necessary for encryption (filename may be hidden from URL this way). - plugin XEP-0446: fix wrong element name - plugin XEP-0447: source handler can now be registered (`url-data` is registered by default) - plugin XEP-0447: source parsing has been put in a separated `parse_sources_elt` method, as it may be useful to do it independently (notably with XEP-0448) - plugin XEP-0447: parse received message and complete attachments when suitable - plugin XEP-0447: can now be used with message attachments - plugin XEP-0447: can now be used with attachments download - renamed `options` arguments to `extra` for consistency - some style change (progressive move from legacy camelCase to PEP8 snake_case) - some typing rel 379

=============================
identity: identity management
=============================

Identity use several XMPP extensions (like vcards) to retrieve or set informations about
an entity. For now it's really basic and only nickname and avatar are managed.

get
===

Retrieve informations about the identity behind an XMPP entity. You only have to specify
the jid of the entity, and you'll get (if set) his/her/its nickname and data about the
avatar.

When available, cached values are returned by defaut. If you want to ignore the cache, use
the ``--no-cache`` option (of course this can result in more network requests).

example
--------

Get identity information about an entity::

  $ li identity get somebody@example.org

set
===

Set identity data to the server, using various XMPP extensions. So far, you can only
change the nickname of an entity using ``-n, --nick`` or or more times

example
-------

Set 2 nicknames for default profile::

  $ li identity set -n toto -n titi
