Align runtime and React view functions

[andrejewski]

The raj/runtime renderer should be called view. I think both words are vague enough and "renderer" makes Raj sound too cool and complicated. I have also flipped the call order of the renderer which was (dispatch, state) and now (state, dispatch). That was an ordering so poor, I even documented it wrong in the README originally.

This consistency is also important for me/library authors who now do not have to care about if people are using the raw runtime, React bindings, or something else. The view is the same everywhere.
