mappings/VegX-VegBIEN.stems.csv: project: Mapped sourceaccessioncode. This entailed adding a distinguishing suffix to the projectname input mapping.

mappings/DwC2-VegBIEN.specimens.csv, VegX-VegBIEN.stems.csv: Removed all manual mappings to datasource_id now that datasource_id is auto-populated, both on the VegBIEN output side and the DwC/VegX input side. This should greatly simplify many of the mappings!

db_xml.py: put(): Don't suppress exceptions thrown by sql_io.put_table() by passing them to on_error(), because some exceptions indicate unrecoverable database connection problems such as a broken connection, which should abort the import

db_xml.py: put(): Support datasets with no rows, where root.firstChild == None. Documented that to use an entire XML document, you need to pass root.firstChild rather than root.

inputs/import.stats.xls: Updated with stats from latest import. Note that the import now includes CVS.

README.TXT: Documented that the PostgreSQL server should be restarted after installing system updates that may affect it, to avoid spurious errors that crash the import but go away upon reimport

Regenerated vegbien.ERD exports

schemas/vegbien.ERD.mwb: Fixed lines

schemas/vegbien.ERD.mwb: Synced with schema

bin/map: Call sys.stdout.flush() after every call to sys.stdout.write() to avoid interleaved stdout/stderr output due to stdout buffering
