lib/runscripts/local.run: moved log_sql (), pg_* () to lib/util.sh because these do not depend on local external scripts in bin/

lib/runscripts/local.run: added pg_copy_to (), pg_header (), pg_export_table_no_header (), pg_export_table_to_dir_no_header ()

lib/runscripts/local.run: added mk_schema_esc, mk_table_esc aliases as shortcuts for `local *_esc; mk_esc_name *`

lib/util.sh: self_not_included (): added support for loading newly-defined aliases for use in functions in the same file, and documentation for how to do this

lib/runscripts/local.run: psql (): output only the query results to stdout (using --output), and redirect everything else to stderr

added /exports/

lib/runscripts/local.run: added log_sql (). mysql (): don't echo SQL commands when not in verbose mode. this is needed to support commands that use the query result in a $() expression, and should not have echoed commands cluttering up stdout. (unfortunately, the SQL commands are echoed to stdout rather than stderr.)

schemas/vegbien.sql: range_modeling_input: use analytical_stem instead of analytical_stem_view because it takes a long time (~2 min) to get a row from the left-joined view, due to the large number of joins and large number of rows in the joined tables

web/links/index.htm: author comments at beginning of bookmark desc: start with a line containing only dashes (-) rather than a blank line, because a newline will be trimmed away on reimport into Firefox, such that reexporting it will lose the author comment indicator
