mappings/Makefile: VegCore.tables.csv: Exclude ambiguous table names, which should not be part of the tables summary (as neither are table synonyms)

input.Makefile: $(translate?): Merged with $(translate), which is not used independently

input.Makefile: Use new translate_ci instead of translate

mappings/Makefile: Use new translate_ci instead of translate

Added translate_ci

mappings/VegCore-VegBIEN.csv: institutionCode list->sourcename mapping: _split(): Also match ; as a separator, and match separators with or without a following space

mappings/Makefile: Added target to create Veg+-VegCore.csv from VegCore.htm, initially commented out until all the synonyms in the existing Veg+-VegCore.csv are added to the VegCore data dictionary <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCore_data_dictionary>

Added redmine_synonyms, which translates a Redmine HTML page to a thesaurus

lockfile: Linux: Documented why newgrp and recursive invocation of lockfile are needed

lockfile: Linux: Fixed bug where need to change primary group of the dotlockfile process to the group of the dir to contain the lockfile, because dotlockfile otherwise reports a "permission denied" error (even though the directory is actually writable, dotlockfile thinks it isn't). Running dotlockfile with a different primary group is complicated because newgrp, the command that does this, does not pass arguments to the new process, so they must instead be passed via environment variables and a recursive invocation of lockfile (with the $inner recursion flag set). Additionally, exec cannot be used to propagate the PPID (needed by dotlockfile) because newgrp creates a new process rather than using exec, so it must be manually entered into the lockfile after dotlockfile runs.
