root map: Fill in defaults for inputs from VegBIEN, as well as outputs to it

disown_all: Updated to use main function, local vars, $self, etc. like other bash scripts run using "."

vegbien_dest: Fixed bug where it would give a usage error if run from a makefile rule, because the BASH_LINENO would be 0, by also checking if ${BASH_ARGV⁰} is ${BASH_SOURCE⁰}

postgres_vegbien: Fixed bug where interpreter did not match vegbien_dest's new required interpreter of /bin/bash

vegbien_dest: Changed interpreter to /bin/bash. Removed comment that it requires var bien_password.

postgres_vegbien: Removed no longer needed retrieval of bien_password

vegbien_dest: Get bien_password by searching relative to $self, which we now have a way to get in a bash script (${BASH_SOURCE⁰}), rather than requiring the caller to set it. Provide usage error if run without initial ".".

input.Makefile: Staging tables: import/install-%: Use new quiet option to determine whether to tee output to terminal. Don't use log option because that's always set to true except in test mode, which doesn't apply to installs.

main Makefile: PostgreSQL: Edit /etc/phppgadmin/apache.conf to replace "deny from all" with "allow from all", instead of uncommenting an "allow from all" that may not be there
