Add support for viewing variant details from the WGS variant calling

[Nicklas Nordborg]

We would like to enabled the "More information..." link in Reggie that opens a popup with information about the variant and also include a tab with all information from the VCF file.

We can't do that now since it causes a NullPointerException. This is easy to get rid of, but the information that is displayed need some modifications.

• It is not aware of having multiple samples in the same VCF file. The display takes information from the normal.
• There are fields related to information that is only available in the RNAseq variant calling

Export "Description" from the meta-headers in the VCF file. The description is used as a hover text to display some information about each data field from the VCF.
