input.Makefile: Maps building: %/.map.csv.last_cleanup: Removed no longer needed subtraction of automapped entries, because information about unmapped and new terms is now available in unmapped_terms.csv and new_terms.csv

README.TXT: Data import: `make backups/download`: Removed '&' because running the command in the background prevents rsync from providing a continuously updating progress indication (because a backgrounded process's stdout is not a TTY)

mappings/VegCore-VegBIEN.csv: Removed no longer needed /_simplifyPath:[next=parent_id]/path expressions in specific paths because parent_id forwarding is now set globally for all paths in the map root

mappings/VegCore-VegBIEN.csv: Added /_simplifyPath:[next=parent_id]/path to root so the returned subplot location will be its parent location if there is no subplot name or ID (indicating that that particular plot did not have subplots). Note that this also causes the parent_id forwarding effect to occur for all other tables containing parent_id, which will help prevent similar issues with subplot events, etc. This will hopefully fix the SALVIAS.plotObservations bug where some organisms did not have a subplot #, causing the subplot location to become NULL and causing the corresponding locationevent rows not to match the locationevent_unique_within_location index filter condition (which requires a parent_id), which caused multiple output table pkeys to be returned for those rows, violating the locationevent_pkeys temp table's primary key.

mappings/VegCore-VegBIEN.csv: namedplace elements: _simplifyPath() calls: Removed no longer needed `require` arg, and removed no longer needed table suffix from `next` arg

inputs/import.stats.xls: Updated with stats from latest import

input.Makefile: Maps validation: $(newTerms): Fixed bug where tail with positive offset needs -n flag

Regenerated/modified inputs/*/*/src.csv to use the self-mapping format used by the new automapping mechanism

src_map: Map source columns to themselves so that src.csv can be used directly with the new automapping mechanism

input.Makefile: Maps validation: %/new_terms.csv: Remove terms which are also in %/unmapped_terms.csv, because terms are not considered new (i.e. potential Veg+ terms) until they have been mapped to an existing Veg+ term. Being unmapped has a higher priority than being new, because it affects the current datasource itself rather than the easier mapping of future datasources.
