schemas/Makefile: Installation: py_functions/install: Removed `env public=`, which is not needed since $(psqlAsAdminVegbien) does not use psql_script_vegbien (which uses $public)

export_analytical_db: Use vegbien_dest to set the default value for $public

README.TXT: Data import: If many inputs have errors: Updated command to `make schemas/$version/uninstall` because the current import's schema is now named $version

schemas/Makefile: Installation: $(schemas), $(schemasReversed) (used e.g. by `make schemas/reinstall`): Removed public so that when `make schemas/reinstall` is run before an import, it will not remove any active (published) import which resides in the public schema

README.TXT: Schema changes: Reinstall public separately from the other schemas so that it will still be reinstalled when schemas/reinstall excludes the public schema to avoid removing any active (published) import

vegbien_dest callers: Removed no longer needed explicit setting $prefix to "", because this is now the default value

vegbien_dest: Changed default $prefix to "", so that the majority of callers don't need to manually set $prefix to "" to avoid it defaulting to out_

README.TXT: Data import: Use env var $version, which is now set by import_all, instead of manually inserting the version for <version>

vegbien_dest: Also export $version

import_all: Run the import directly into a new, already-versioned public schema. This removes the need to manually rename the schema after import, and allows the backup commands to use the stored $version shell variable to refer to the last import.
