Merge LabAnalysis_FeatureBranch2 to Master SpecimenBatchPositions table.

I think this relatively minor change now completes the LabAnalysis schema! and potentially adds nice functionality to other uses.

The recent addition of the FeatureActions table (replacing the
FeatureActionResults table), allows us to solve an important need in
every laboratory.  See

* Deleted the long Note, and rearranged the diagram a bit.
* I made a tiny change in ODM2DataQuality.ResultNormalizationValues.  I
made the ResultID a primary key in this table, following the
conventions that we have used for Specimens and Sites.
