/README.TXT: Maintenance: to synchronize a Mac's settings with my testing machine's: use better bin/sync_upload instead of put

/README.TXT: Maintenance: to synchronize a Mac's settings with my testing machine's: removed no longer needed inplace=1, because the VirtualBox VMs now all use a snapshot covering the full disk, so that the full disk is not altered (removing the need to optimize backing up a large file) and just the diff files need to be backed up each time

bugfix: lib/sh/util.sh: sed: must use alias instead of function because function causes segfault in redir() subshell when used with make.sh make() filter (may be bug in bash?). this involves translating `unset LANG` to `env LANG=` (`env -u` to unset a var isn't supported on Mac, but fortunately sed treats LANG="" the same as unset LANG).

added planning/goals/BIEN_3_derived_data_products_NormalizedDB_only.docx from Brad's e-mail

bugfix: lib/sh/util.sh: sed: unset LANG to avoid "illegal byte sequence" errors on invalid UTF-8 for LANG=*.UTF-8. these occur e.g. with MySQL data that is in Latin-1.

lib/sh/util.sh: sed: use function instead of alias so that env can be set up before calling sed

lib/runscripts/table.run: map_table(): run map_table repeatedly until no more renames are made: added command to do this

lib/runscripts/table.run: map_table(): documented that collisions may prevent all renames from being made at once. if this is the case, map_table must be run repeatedly until no more renames are made. collisions may result if the staging table gets messed up (e.g. due to missing input columns in map.csv).
