Merge of new VCF features

Command line script, modules and tests to write multiple Fluidigm/Sequenom CSV files in iRODS into a single VCF file, and run a consistency check between samples using bcftools.

VCF tests require the bcftools module version 0.2.0-rc9 to run: /software/gapi/Modules/apps/bcftools/0.2.0-rc9
"load bcftools" has been added to the Jenkins config for genotyping tests.
