input.Makefile: Staging tables: import/install-%: Output load status to log file if log option is set

Scripts that are meant to be run in the calling shell: Fixed bug where running the script inside another script would make the script think it was being run as a program, and abort with a usage error

Scripts that are meant to be run in the calling shell: Fixed bug where running the script as a program (without initial ".") wouldn't be able to call return in something that was not a function. Converted all code to a <script_name>_main method so that return would work properly again. Converted all variables to local variables.

env_password: return instead of exit if password not yet stored, in case user is running it from a shell without the initial "-" argument. (This would be the case if the user is just testing out the script, instead of using a command that env_password directs them to run.)

env_password: Use ${BASH_SOURCE⁰} for $self and $self for $0. return instead of exit on usage error in case user is running it from a shell.

stop_imports: Use ${BASH_SOURCE⁰} for $self and $self for $0

import_all: Use new with_all. Use ${BASH_SOURCE⁰} for $self and $self for $0.

Added with_all to run a make target on all inputs at once

Made row #s 1-based to the user to match up with the staging table row #s

bin/map: Fixed bug where limit passed to sql.select() was end instead of the # rows, causing extra rows to be fetched when start > 0. Documented that row #s start with 0.
