redmine_synonyms: Don't require ambiguous terms to start with ?, because the ambiguous term for an alternative can be identified simply by choosing the last term that didn't have a type label (previously, this would have been the last term that wasn't h3 or h4)

redmine_synonyms: Use the term's type label instead of its header level to determine if it's a synonym or alternative. This allows header levels to be chosen for presentational reasons rather than being constrained by being parsable.

mappings/VegCore.csv: Regenerated from wiki. The data dictionary has been reformatted to be much more vertically compact, by placing the term type (Synonym, Alternative, etc.) and sources (From:) on the same line as the term. Note that globalUniqueIdentifier_SpeciesLink has been removed from the vocabulary because a definition entry has been added for it (when this entry is missing, the term is incorrectly identified as a primary term).

mappings/Makefile, redmine_synonyms: Updated for new VegCore data dictionary format, which prefixes the term type (Synonym, Alternative, etc.) to the term instead of including it as a section label. This ensures that the term type of a non-primary term is shown next to the term when it is visited via a permalink, which causes the term header to appear at the top of the screen and obscures the section header containing the type.

mappings/Makefile: VegCore.thesaurus.csv: removal of tables: ignore errors if grep found no match

Renamed mappings/VegCore.csv to VegCore.vocab.csv and Veg+-VegCore.csv to VegCore.thesaurus.csv for clarity

mappings/Makefile, input.Makefile: Renamed $(dict) to $(thesaurus) because Veg+-VegCore.csv is actually a thesaurus, not a dictionary

mappings/Makefile: Replaced occurrences of VegCore.csv with $(vocab) and Veg+-VegCore.csv with $(dict)

README.TXT: Maintenance: VegCore data dictionary: When moving terms, check that no terms were lost: Updated steps now that VegCore.csv and Veg+-VegCore.csv are sorted by name, so that a comparison of added/deleted counts is not necessary and a simple `svn di` can be used

mappings/Makefile: Veg+-VegCore.csv: Sort terms by name so that reordering terms in the VegCore data dictionary does not cause Veg+-VegCore.csv to change. This makes it much easier to identify synonyms and ambiguous terms that were accidentally deleted during a data dictionary refactoring. (Note that these are no longer included in VegCore.csv, so this is required in addition to sorting VegCore.csv by name.)
