This introduces the brand new `StatusChatListItem` which can be used
to render channels, one-to-one chats and community channels in Status
applications.
The component can be used as follows:
```qml
import Status.Components 0.1
StatusChatListItem {
name: "channel-name" // name of channel or user
type: StatusChatListItem.Type.PublicChat // GroupChat | CommunityChat | OneToOneChat
image.source: "profile/image/source" // uses letter identicon instead of not supplied
hasUnreadMessages: true // default `false`
badge.value: 1 // default `0`
muted: true // `default `false`
selected: true // default `false`
onUnmute: ... // signal when unmute icon is clicked
}
```
