Title: Implemented o-layers in Nav

It only applies to Nav, not the whole o-ft-header, in case we want to make it a separate module ([#17](https://github.com/Financial-Times/o-ft-header/issues/17)). I changed the o-layers event names to those mentioned in [#1](https://github.com/Financial-Times/o-layers/issues/1)
