priority: all set to 1 initially.

allow MArkersymbol sources to be used to get the gene descriptions. If all fails use Marker symbol as gene description regardless of filters.   Still work in progress

Only store descriptions from certain sources (listed in gene_description_sources()) to prevent e.g. IPI being used for description if there's nothing else found.

Fix to method of finding transcript display xrefs; previously xrefs from same source would not be reliably sorted on query/target identity.

allows the removal of only certain types of seq region attributes from
a slice)

Added RefSeq_dna_predicted & RefSeq_peptide_predicted to priority list (below known RefSeqs and SPTREMBL).

Slight change to description filtering logic; use original unfiltered description if anything survived the filtering.

Added first go at adding triage stuff i.e. why some refseq and uniprot sequences are not found in ensembl. At the moment if there is no match then this is reported else the actual percentages are given for the closet match with the actual cutoff values used.
