Messages (received directly or via MAM) are stored in a backbone
collection that's kept sorted by the message's "time" attribute.
Various parts of the codebase rely on this behavior.
For regular messages, the time attribute is generated by
`moment().format()`, which generates a timestamp in the browser's
local timezone, for example "...+02:00".
For MAM messages, we would previously copy the "delay.stamp" value
into the "time" attribute verbatim. However, that value is generated
by the server and is unlikely to be in the same timezone locale.
ISO timestamps expressed in different timezones cannot be sorted
lexicographically, breaking the premise of keeping the messages
collection sorted by time.
* Rooms Api
number of parameters in the documentation was made 2 from 3 as api which is used to open a room with default configuration has only 2 parameters.
That way we don't lose the user's input values, we avoid flashing and we
avoid unnecessary rendering.
In the process, fixed an annoying issue where Chrome auto-completes
what it thinks is the username into the "Language Tag" field of the MUC
config form.
Instead we tell Chrome that the MUC JID is the username, thereby also
letting it save the password to to that JID.
Looks like the `webkitTransitionEnd` event doesn't fire because `fade`
is already on the modal, so there's no transition, which means that in
bootstrap.native the event doesn't get fired to remove the overlay.
- Let box_id start with char for valid HTML.
- No need to use SHA1 for box id
- No need for the user_id attribute.
- Set nickname when we set the roster contact.
Also...
- _converse.api.contacts.get is now async
- _converse.api.chats.create is now async
This changes the API method's current behavior by not automatically
maximizing (in `overlayed` view mode) or bringing a background chat into
foreground (in `fullscreen` view mode). Instead `force` needs to be set
to `true` for that to happen.
