Track #1570 (search using OMIM id used in URL): added support forsingleSearch=omimGeneAcc, or any searchName (which defaults to
searchTable if not defined in trackDb.ra).  May not be strictly
necessary for OMIM because as Fan found OMIM numeric IDs already
get unique semiShortCircuit hits, but we expect this to be useful
for track-specific links to us in general.
