Better support for innerRef when wrapping function components

Function components cannot have refs so our innerRef prop would break when used with withTheme:

Thanks to @MatthieuLemoine, rather than attaching a ref to stateless function components (which results in a warning) we now pass the innerRef prop to it directly for it to handle. (see #1205)

Smaller changes

• Consistently escape displayNames when creating componentId, thanks to @evan-scott-zocdoc (see #1313)
• Add basic support for style objects in the Typescript definitions, thanks to @nbostrom (see #1123)
