bugfix: *{.sh,run}: use `local` when setting default values for params to prevent these values from leaking into the calling context, where it may have unexpected effects (e.g. pg_copy_to would permanently set $source, which would then be used on the next invocation of pg_copy_to instead of regenerating $source from the next $table value). this involves using ${var-default} or ${var:-default} to return the value to the local statement instead of setting it directly with ${var=default} or ${var:=default}.

*{.sh,run}: commands that take named arguments: usage messages: changed to use simpler bash syntax for specifying command-specific env vars, which does not require a subshell ("The environment for any simple command or function may be augmented temporarily by prefixing it with parameter assignments" <http://www.gnu.org/software/bash/manual/bash.html#Environment&gt;)

schemas/pg_hba*.conf: removed trailing whitespace

schemas/pg_hba*.conf: allow the bien group to access all databases, including test (on the Mac). note that this does not grant access to the vegbank DB on vegbiendev, because that is owned by postgres.

web/links/index.htm: explicitly separate page's description from author comments where needed

web/links/index.htm: use - instead of --- to separate the page's description from the author comments because it's faster to type and one hyphen is sufficient

lib/Firefox_bookmarks.reformat.csv: labeling page's description: don't match descriptions with a leading blank line as an author comment, because sometimes page descriptions themselves start with a blank line. instead, author comments at the beginning of bookmark descriptions should always start with a " or be preceded by a line containing only hyphens (-). note that it was never reliable to use a blank line for this purpose, because it would be trimmed out upon reimport of the HTML file into Firefox.

web/links/index.htm: updated to Firefox bookmarks

inputs/NVS/*/map.csv: Taxon Growth Form: use new _lowercase() to avoid needing to manually map each value that is already valid but just needs to be lowercased

schemas/util.sql: added _lowercase()
