add synonyms from the dead names column. NOTE still need to get the Mapper routine to dump non primary xref synonyms

Fixed bug causing query/target identity to not be considered when choosing gene descriptions.

Do not copy via a specific host (as these now have a max 256 process per user limit). This may be slower than the direct use of a named host (with the nfs directly hanging of it) but will work

commented out locuslink and OMIM as these are not used now. Removed Wormbase and used wormpep_id instead as this will not confilct with the external_db defined values

allow isa check also. Xref system uses a dbadptor as base class so has a different name but still isa

Added RefSeq_peptide_predicted and RefSeq_dna_predicted (as type 'PRED') to distinguish predictions from KNOWN RefSeq entries.
