constantTimeDispatcher lets you poke a specific react component to do something
without having to do any O(N) operations. This is useful if you have thousands
of RoomTiles in a RoomSubList and want to just tell one of them to update,
without either having to do a full comparison of this.props.list or have each
and every RoomTile subscribe to a generic event from flux or node's eventemitter

Also get rid of the "up" arrow so as not to indiciate direction. This is important because in future the RM will not be based on what has been paginated into the client (but instead RM will be handled server-side) and thus we cannot assert any kind of direction on it relative to the events in the viewport.
Use an action and force an update when zeroing the number of notifications in a room. This is better than waiting for a `render` to happen at some point. This will hopefully fix https://github.com/vector-im/riot-web/issues/3257
- Set the verb for the people section to "tag as direct chat". This requires some CSS modifications to Riot because it's a long bit of text relative to, say, "demote".
- Because it's quite useful to be able to set the DM status of a room with just a boolean, add a convenience function for guessing a DM member and setting the DM flag on that room with the resulting member.
This does two things:
- Sets `editable` to true for the "People" `RoomSubList` so that people can be dragged to favourites. This has the downside that you can drag a "People" to "Rooms", but it won't set the direct chat flag. This is because im.vector.fake.direct != m.direct, sadly.
- Sets `alwaysShowHeader` to `true` so that the `IncomingCallDialog` can be showneven when there are no people in `sortedList`. Fixes https://github.com/vector-im/riot-web/issues/2956.
When creating a new chat with one person, show a dialog that asks the user whether they'd like to use an existing chat or actually create a new room.
Fixes https://github.com/vector-im/riot-web/issues/2760
- Shift to the left _before_ adding an avatar so that there are always `MAX_READ_AVATARS` visible, instead of there being `MAX_READ_AVATARS + 1` avatars displayed following the first "collapse".
- Use `right` instead of `left` so that double-digit remainders don't get overlapped.
