blast-result-view : make transient dataset and block ids unique by pa…

…rent

 ... to address issue of subsequent results not displaying features/triangles.
dnaSequenceSearch.bash : pass datasetId to dev_blastResult, so that multiple results can be simulated in development.

blast-results-view.js : viewFeatures() :
append parentName to datasetName for transient datasets, to make them distinct by parent.
add featuresU : prepend dataset.id to features[*].blockId

transient.js : pushBlockArgs() : blockId : prefix datasetId, so that results for different parents are distinct.
