Gene page improvements

[onursumer]

• Update Mutation Status values as: Somatic, Germline - Pathogenic, Germline - Benign/VUS
• Add Cancer Type column. (List all non-zero variant tumor types)
• Only show Pathogenic Germline by default. (Just update default filter) (Decided to revert this)
• Remove the Penetrance column and add the H/M/L/U to Annotation column
• Rename % to % Prevalence
• + expanded table: Exclude tumor types with 0 variants.
• If GenomeNexus has ClinVar pathogenicity; add that under Annotation column.
• Hide (or remove?) dbSNP ID and ClinVar ID columns.
• Add HGVS columns (Add hgvsg and hgvsc to gene page #71)
• Show germline mutations in table on top (sort by germline)
