These components are used to render the chat info in the top bar of the chat view.
`StatusChatInfoButton` is an clickable button that will open chat info dialogs.
Closes#923
This component introduces `StatusLetterIdenticon`, `StatusImageIdenticon`
and `StatusIdenticon`.
- `StatusLetterIdenticon` renders an identicon with a single letter based on a
name.
- `StatusImageIdenticon` renders an actual image based on an identicon URL
- `StatusIdenticon` is a composition of the former both, but with a loading mechanism
to decide which should be rendered
The commit also ensures all of these components are used respectively throughout
the application.
