Playback return values by parameter values instead of order

[mkotsbak]

It should be possible to specify that all or some of the dependency calls (maybe by using annotation those places) are played back by the parameters they get instead of just the sequence they were called.

If there are several matches for the same parameters, the matches should be played back in order (in case there is some state or randomness in the dependency).

This may not be the right way to go. Too much flexibility will hide errors, when the whole point is regression test that the application doesn't change.

Anyhow, there are a few things regarding the playback that we may want to leave open. As the solution evolves, I expect the playback strategy to be encapsulated in a strategy. Adding alternative strategies may then be an option.
