Reduced the memory allocation in the TimeseriesOutputComp in common use cases. (#1096)

* Modified TimeseriesOutputComp so that it doesn't allocate unnecessary matrices.

This is especially important in the Birkhoff transcription where the pseudospectral differentiation matrix is large and dense.

In cases where the component was simply echoing its inputs as outputs, the interpolation matrix is not needed.

If no rate outputs are needed, then the differentiation matrix is not needed.

In light of the Birkhoff transcription, problems should be formulated to remove the need for differentiation matrices.
