Apply patch from Aaron S. Joyner to improve user friendliness of database build script

- validate that the fts-config.sql script exists for the specified database version
- if it does not, detect the latest available version, warn the user, suggest aborting, offer to continue w/ the latest available version
- rework call of psql to avoid PGPASSWORD on the command line, visible via ps
- warn user if psql fails attempting to import any of these files for reasons such as couldn't connect, or file not found (not sql script errors)
- provide commented out option to fail on sql script errors, for future convenience when the scripts run cleanly w/o errors
- limit line length to 80 characters (a nearly unbreakable habit from work)
- remove database version entirely from the user interface, down to build-db.sh.  This makes minor removals from:
  - install.sh
  - config.sh
  - install.conf.default
  - Open-ILS/src/Makefile
  - Open-ILS/src/extras/import/build-oils-db.sh
- implement automatic detection of PostgreSQL database version
- abort if we can not detect the db version, providing the user with our best guess (it's probably not going to be, but oh well)
- maintain fallback in the case of missing fts-config.sql for specific db version, with big shiny warnings adapted to the autodetection
- abort if no fts-config.sql files exist
