chore(release): set version to 1.9.0 [skip ci]

## [1.9.0](v1.8.1...v1.9.0) (2020-06-27)

#### Features

* **Interactables:** apply more specific namespace to interactables ([0f8b8d5](0f8b8d5))
  > Previously, the Interactables were in a namespace that was at a higher level of the Interactors whereas Interactables should be at the same level.
  >
  > There is already an Interactables namespace used by both interactors and interactables so the best solution is to just have a double Interactables.Interactables namespace. Whilst this looks a bit strange it at least buckets the code at the correct level.
