Changes

#800 Could not register successfully in ejabberd 17.01
#949 Don't flash the roster contacts filter (i.e. hide by default)
#951 Duplicate messages received in an MUC chat room.
#953 MUC "Features" displayed when exiting configuration
#967 Rooms list doesn't show when the server doesn't support bookmarks
Don't require auto_login to be true when using the API to log in.
Moment locale wasn't being set to the value passed via the i18n option.
In the chat heading, two avatars sometimes get rendered.
Refetch the roster from the server after reconnection.
From the perspective of the XMPP server, this is an entirely new login,
and therefore as per RFC-6121
the roster SHOULD be queried, making the client an "interested resource".
Otherwise connected contacts might not get your presence updates.
The way the archive ID of a MAM message is specified, has changed.
See https://xmpp.org/extensions/xep-0313.html#archives_id
Fixed error building DOM toggle_chats.html span.unread-message-count class attribute
Bugfix. In a MUC the /help command didn't render properly.
The /voice MUC command didn't set the right role in order to grant voice again.

Emojis are now sent in unicode instead of short names
#314 Add support for opening chat rooms with a URL fragment such as #converse/room?jid=room@domain
and private chats with a URL fragment such as #converse/chat?jid=user@domain
#828 Add routing for the #converse/login and #converse/register URL
fragments, which will render the registration and login forms respectively.
New configuration setting view_mode
This removes the need for separate inverse.js and converse-mobile.js
builds. Instead the converse.js build is now used with view_mode set to
fullscreen and mobile respectively.
Fetch VCard when starting a chat with someone not in the user's roster.
Show status messages in an MUC room when a user's role changes.
In MUC chat rooms, collapse multiple, consecutive join/leave messages.
Performance improvements for rendering private chats, rooms and the contacts roster.
MUC Leave/Join messages now also show a new day indicator if applicable.

New API method _converse.disco.supports to check whether a certain
service discovery feature is supported by an entity.
New API method _converse.api.vcard.get which fetches the VCard for a
particular JID.

#984 Improve loading of archived messages via "infinite scroll"
Use CSS3 fade transitions to render various elements.
Remove Login and Registration tabs and consolidate into one panel.
Show validation error messages on the login form.
Don't hang indefinitely and provide nicer error messages when a connection
can't be established.
Consolidate error and validation reporting on the registration form.
Don't close the emojis panel after inserting an emoji.
Focus the message textarea when the emojis panel is opened or closed.
MUC chatroom occupants are now sorted alphabetically and according to their roles.

Converse.js now includes a Virtual DOM
via backbone.vdomview and uses
it to render various views.
Converse.js no longer includes all the translations in its build. Instead,
only the currently relevant translation is requested. This results in a much
smaller filesize but means that the translations you want to provide need to
be available. See the locales_url
configuration setting for more info.
The translation machinery has now been moved to a separate module in src/i18n.js.
jQuery has been completely removed as a dependency (still used in tests though).
