Usage: ```qml StatusModal { header.image.isIdenticon: ... // or header.icon.isLetterIdenticon: ... header.icon.background.color: ... } ``` Closes #269
As discussed in #237, this is needed for consumers to access content children from outside `content`. Usage: ```qml StatusModal { id: modal content: StatusBaseText { text: "Foo" } rightButtons: [ StatusButton { text: "Change text" onClicked: { modal.contentComponent.text = "Bar" } } ] } ``` Fixes #237
