v0.29.0 - the on-screen keyboard

P37's touch half: the on-screen keyboard. Rows of keys as data (KeyboardLayout/KeyboardKey), rendered through the theme's own Button, each tap feeding the same core.Input paths a physical key travels - dispatchText for a typing key, the new dispatchAction for an action key - so a TextPrompt cannot tell the two apart. TextPrompt grows a keyboard option that hosts one beneath the field and resizes the window to fit it, UPPERCASE_KEYBOARD is one shipped default, and the interface example's Name prompt carries it as the reviewed touch pattern.
