In fetch_by_Transcript, updated a throw message so that it says which transcript_id is causing problem

generate a file of %id's and the accession names from the map files. Only process those from the list (acc_file) so lists can be made for seperate sources if wanted

Changed field separator in input file from one tab to one or more whitespace characters; makes input file formatting less error-prone.

Making mRNA xref dependent on peptide isn't needed and is actually quite confusing on the web display.

Deal with 2 different sources instead of just one - RefSeq_peptide & RefSeq_dna - since Mart needs one type per source.

Modified appropriate source_url entries as well.

fix bug that if -dumpcheck set and files not found then the script failed instead of dumping the files

Species-specific display_xref priorities for tetraodon. Same as in BasicMapper but Genoscope_* order reversed.

Make all external_synonym entries unique.

Corrected location from which display_xref .sql files are uploaded.

fix for no species being specified and more than one core database bring called (connection was not dropped)

Fixed calculation of transcript display_xrefs; wasn't considering translation-transcript relationship properly.

Now use | as separator character in composite hash keys; : was a bad choice since it appears in GO xrefs.

Don't write xref/object_xrefs for sources that have no corresponding external_db entry (but warn about this).
