- Add a test case.
- Don't allow passing of `attrs` to `chats.open`. Not sure yet of the
  implications of this.

Resolves #760.

Not when the connection failed due to other reasons (like wrong credentials).

when `auto_reconnect` is set to true.

The ChatRoomView renderDragResizeHandles is only rendering the top resize handle (<div class="dragresize dragresize-top"></div>). the insert was only inserting the first child of the dragresize template, which has 3 children. Modified to insert the whole the div that the dragresize template gets inserted into.

Prosody doesn't handle it if we set the affiliation for multiple JIDs in one
stanza, so we need to send a stanza for each JID.

Apparently the mailing list hasn't been working since months.

Now that we are sending multiple IQ stanzas when setting affiliations.
We now again have a sendAffiliation method, so we use that.

At least for Prosody.

This changed required me to go back to an array of maps instead of a single map
to store jids and affiliations.

When inviting someone to a members-only room, you only want to add an
affiliation of 'member' if they don't already have any other affiliation.

So we need to ignore the "new" member if they're already on *any* of the lists.

Make the delta algorithm simpler. Fixed some delta bugs in the process.

One for each affiliation (member, owner, admin).

Unfortunately Prosody doesn't give you correct results if you query for all
three affiliations in one stanza.

We'll have to see whether setting all three in one stanza actually works.

As required by XEP-0045.

This requires that we first fetch the existing member list, compute the delta
and then send that if there is one.

When it's clear that a previous teardown didn't happen.
So that objects can be garbage collected and that obsolete event handlers don't
fire anymore.

It gets created anew when reconnecting or logging in.
