Rendering tricks for improving workflow:

- Button option "Single" in render-layer panel will enable to only render
  the currently indicated render-layer. It will also skip compositing.

- Brought back the 'Local View' render. This will only render the visible
  objects, but with lights from the original view-layers.
  To make the option useful, it also temporal enables 'Single', which has
  the a disadvantage that you need to set the correct render-layer.

  It is a bit a tricky option though... since its quite invisble and
  confusing for people who don't know the feature. This might become either
  a button in 3d header, or use a popup requester to confirm, or... will
  need to think over!

At least; both options display in render window a text to denote the option.
