starting refactor for new sources, including multiple resources per genotype
added MPD as a geno-pheno source, with logo.  also altered the column headers 'model species' -> 'species'
added MPD to sources and xrefs.  changed cutoff to >3s.d. for fetching MPD data
added clinvar variant data closes #357. refactored a bit of makeGenotype and SequenceVariantPhenotypeAsAssoc. added helper function to make list of references.  added new cols to the disease-variant tab to show including band, partially addresses #262.
added IMPC as a new data source.  a bit of geno-pheno refactoring.
partial refactor to remove repeated code for literature tabs
refactored literature calls: reduced number of pmid service calls, cleaned up code; added new source:  gene2pubmed; refactored hpo disease-phenotype to have onset labels, and evidence code ids; added impc source image
a variety of changes and adding new data - some refactoring to fetchGeneInfo
added gene reviews config and image
cleaned up literature list, removed some logging, removed genomic location from variants, showing submitter sources from clinvar, show more descriptive information about model derivation
increased api number
Adding many new sources, and a refactor of several methods
Merge branch 'newsources'
