input.Makefile: $(tables): Fixed bug where need to use $(importTables) instead of $(tables) in all places that should use only imported tables, rather than just in the import process itself

input.Makefile: Import to VegBIEN: Added support for tables which should be installed but not imported, but which must be installed after tables which are imported rather than before. This currently applies to geoscrub.geoscrub_cultivated, which depends on geoscrub_cleaned_unique (and therefore must be installed after it), but which should not be imported because it's used directly as a lookup table by analytical_stem.

inputs/VegBank/vegbank.~.clean_up.sql: Documented that plots with confidentialitystatus >= 4 are not deleted if their embargos have already expired. This applies to the Shenandoah NP data, which has confidentialitystatus = 5 but is no longer embargoed according to the embargo table

inputs/SALVIAS/: Mapped unmapped fields with a VegCore/VegBIEN equivalent. plotMetadata_/: Remapped life_zone to communityID because it is now alt-ed together with vegetation*, and thus not just a description with life_zone_code as its globally unique name.
