Easy way to close all/a lot direct messages

[func0der]

People usually have a lot of direct messages open.

I want to propose that there should be an easy way to close them all up, if one is done with them.

One of two ways would be great:

1. Either have a "close all" button beside "Direct Messages" to close them all

2. have a dedicated "x" button beside each chat, so one can simply click the same point in the list over and over again to close all chats at once.

3. option would not lead to "too many request" failures, so I guess that would be the preferred way.

4. option would be more versatile
