David pointed out that it is inappropriate to show Hardy-Weinberg equilibriumfrequencies on the VCF details page unless the VCF data are from a population
study -- so at this point, pretty much only 1000 Genomes.  So I added a new
trackDb setting for vcf/vcfTabix, showHardyWeinberg, and added it to the
1000 Genomes track def.
