Force the loading of external synonyms before getting the code to store them. Otherwise we incorrectly retrieve external synonyms from the source database with a newly assigned ID

for multiple gene numbers the zebrafish naming need to use the original name and not the modified one in future gene numbers.

Added code to fix issue with Corf genes in zebrafish. The gene names were not being modified to look like hsC*orf*-like. This now works.

Add projected xrefs to genes rather than transcripts by default if there is no equivalent type in the target database.

Added code to delete names/GO terms if the -delete_only option is specified. Added code to check whether
-registryconf is submitted as a string from the submit_projections.pl script or as a file on the command
line.

Use the translations of the _canonical_ transcripts of the source and target genes as the source of GO terms to project, rather than simply the longest translation in each, which was a bit arbitrary and didn't alway work.

Also make the print option for GO term projection a bit more verbose - aids debugging.

Skip projection of genes from sources with "clone" in the db name - should stop mouse clone names being projected to rat & kangaroo rat.

Set gene description to NULL and status back to KNOWN_BY_PROJECTION when deleting previously-projected xrefs.

Skip genes that are listed in Compara but aren't in the relevant core databases. Shouldn't be necessary in production runs but makes testing with previous Compara versions easier.
