affix bottom bounds fix
Fixed CollapsableMixin to set dimension css style to 'auto' when the transition to the expanded state is complete.
Fixed `ButtonToolbar` displayName

Closes #220
Fix for manual mode of OverlayTrigger.

Before this fix it was not possible to refer to the component wrapped by the OverlayTrigger using the ref property, because it was not cloned using cloneWithProps.

Now, in manuel mode,  we just return the unmodified child which will still have the ref and all children.
