Caliburn.Micro 3.0.3

This is a very small release that reverts #339.

This release changed behavior so that views were resolved from the container in the same way as view models. The change in behavior caused problems for applications using containers that threw exceptions on failure to resolve a dependency.

This change should have been considered a breaking change and left to 4.0.0 and considered more seriously. For that I apologize.

It's also contains a typo in documentation fix. #402
