What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)
This removes the abstract base class we use in ReactiveCommand.

What is the current behavior? (You can also link to an open issue here)
There is a abstract base class. Users can introduce subtle bugs by using it directly in their code. It was meant for interop with the ICommand but now ReactiveCommandBase<TParam, TResult> now implements that logic. There is also a interface allow some of the Command Binding code to keep functioning and exposes the observables for the user. It's deliberately not derived from ICommand due to us wanting the separation.

What is the new behavior (if this is a feature change)?

What might this PR break?
Users who have a derived off the abstract base class. They will have to change their classes to derive from ReactiveCommandBase<TParam, TResult> now.

Please check if the PR fulfills these requirements

  • Tests for the changes have been added (for bug fixes / features)
  • Docs have been added / updated (for bug fixes / features)

Other information:
Docs have already been modified to show the non-abstract class use.

This relates to reactiveui/rfcs#19

Glenn. This LGTM. I would say we need another member of the @reactiveui/core-team to make sure there are no major concerns.

Looks good, assume this is a reasonably major version change?

Will take us to 9.1 or 10. If we follow semantic versioning I guess 10
