bugfix: postprocess(): moved $can_test flag from import() to this function because it is used here

lib/runscripts/table.run: import(): moved postprocessing commands to separate postprocess() function that can be invoked on an already-imported staging table to avoid running the load_data() target. this is especially useful when running the postprocessing on a working copy without the unversioned data files, for datasources whose load_data() target would otherwise try to download the files because they don't already exist.

lib/runscripts/table.run: postprocess(): renamed to custom_postprocess() since this runs only the datasource's custom postprocessing commands, not all the postprocessing commands including map_table, mk_derived

lib/runscripts/util.run: added , function, which treats each of the command-line args as commands the way make does (instead of as args to the same command, the way runscripts do)

lib/sh/util.sh: moved runscript-related commands to lib/runscripts/util.run because these only apply to runscripts

bugfix: inputs/*/*/map.csv (e.g. inputs/GBIF/raw_occurrence_record_plants/map.csv): remapped author to scientificNameAuthorship rather than authors, which it had gotten incorrectly automapped to. note that the VegCore term authors has now been renamed to data_authors to avoid ambiguity, but incorrect automappings resulting from it had not yet been fixed.

bugfix: inputs/GBIF/raw_occurrence_record_plants/run: updated herbaria.ih column names for staging table column renaming

bugfix: inputs/GBIF/table.run: need to include lib/runscripts/mysql.table.run instead of table.run (table.run was accidentally substituted when inputs/.NCBI/table.run was copied to all new-style datasources

backups/Makefile: %.backup/restore: documented runtime (11 h; ~5 h to insert data). note that this is still much shorter than re-running column-based import.

planning/workflow/bien3_architecture.pptx: exported from bien3_architecture.odp, as requested by Martha. the .pptx format is buggy and doesn't show the slide thumbnails on the slide notes view, but will have to do as .ppt (the older MS PowerPoint format) doesn't support the graphics.
