xml_func.py: process(): In row-based mode, when trying to evaluate function using DB, preserve unknown funcs because these might be built-in functions of db_xml.put(). The sql.DoesNotExistException should be raised again when db_xml.put() is run and it verifies whether the function is built-in or not (e.g. _simplifyPath is now built-in, for column-based support). See db_xml.put_special_funcs for built-in functions.

db_xml.py: put(): Fixed bug where strings starting with "$" were interpreted as input columns in row-based mode (this should only apply to column-based mode). Explicitly store whether in row-based mode in is_literals var (similar to is_literals in sql_io.put_table()).

sql_io.py: put_table(): unrecoverable errors: Returning default value: is_literals: Remove column rename from default value so it doesn't get treated as a column by db_xml.put() (which is handled differently from a literal value)

db_xml.py: put(): put_(): Removed no longer needed in_row_ct_ref param, which is only used by put_table(). Rewrapped function body.

sql_io.py: put_table(): ignore(): literals: Only replace invalid literal with NULL or remove row if that column actually contains the invalid value in question. This handles the case where all columns are being ignore()d because the specific column couldn't be identified, and this was not the invalid column.

mappings/VegX-VegBIEN.stems.csv: plot: Mapped note

mappings/VegX-VegBIEN.stems.csv: plot: Added landform mapping

schemas/vegbank.ERD.pdf: Auto-repaired with Adobe Reader so that the repair message doesn't pop up whenever it's opened

schemas: Added vegbank.ERD.pdf so the VegBank ERD is easily accessible when mapping

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