* 'master' of https://github.com/mpi2/PhenotypeArchive:
  Added convenience method to SignificantType to get mappings from phenstat wording from the database to Terry approved wording.
  Changed the way the phenotype icons are colored on the gene page.
  Fixed bug in testPreQcGraph() that was only fetching postQc links and thus failing to run any test iterations.
  Reduced iterations to 20 max as most errors occur almost immediately within the first couple of iterations.
  Increased timeout from the default 4 seconds to 1 minute, as some of the pages can take a long time to load.
  Reduced PhenotypeAssociationsTest testTotalsCount to 50.
  Reduced iterations.properties iteration counts for faster test execution. Most of the failures occur within the first 10 iterations.
  unidimensional chart bug not showing because rgba colors are different strings to just colors from the ChartColors class. so we need JSONArray for the rgba colors but not normal colors!
