Summary: public
It is now possible to display and edit rich text inside a multiline `<textInput>` by nesting a `<Text>` node inside it.
Note that this doesn't yet provide everything needed to build a full rich text editor (as there is no facility to capture or control the selected text range, or insert/remove text) but it does make it possible to apply token-based styling to text as the user types.
See the 'Attributed text' example in the UIExplorer > TextInput demo for details.
