feat(StatusRoundedImage): introduce identicon support

This just introduces a new `StatusImageSettings` property `isIdenticon`
which can be used to determine whether a `StatusRoundedImage` should
render with a background + border (which is the case for identicons).

It also updates the `StatusChatList` delegate to consider that property
and have it properly decide how to render the UI.

Closes #173
