Had previously hardcoded datatype for analyze pages as phenotype
Fixes #282 (analyze page species column in results)

1. mapMatchIdentifierToTaxon function now returns correctly formatted taxon object. taxon.id needs to be a string of format /NCBITaxon:\d+/, not an integer.
2. mapSpeciesIdentifierToTaxon function now maps a species number to a taxon object.
3a. If query specifies one species, analyze table view show single species above the results table.
3b. If query specifies more than one species (all), analyze table displays species in column for each result.
4. analyze.mustache template contained incorrect option value. Human was set to 9096 (some sort of pheasant bird) rather than 9606 (Homo sapiens).
5. species columns are now sortable.
