mappings/: Removed no longer used plots, organisms, and stems maps, which were copies of the specimens map

input.Makefile: Core maps: Always use the specimens "table", since there are now no longer separate mappings for different tables, and the other tables' maps in mappings/ are merely copies of the specimens table's map

input.Makefile: Removed no longer used custom via maps code, so that map files no longer need a prefix (which is always the same) specifying that they map through Veg+. Veg+ thus serves as the single gateway to VegBIEN, which avoids ever again having to maintain two copies of the mappings, as was the case when DwC and VegX XPaths were separate gateways. This will assist in untying the complex mapping logic in input.Makefile from file naming conventions in mappings/, and simplify the task of grouping each map with the CSV it maps.

input.Makefile: Removed no longer used DB inputs section, because all of our inputs are either CSV or (rarely) XML. This removes a significant amount of dead code that will make it easier to refactor input.Makefile to use custom CSV import orders.

mappings/Veg+-VegCore.specimens.csv: Added mappings for miscellaneous terms

mappings/Veg+.terms.csv: Added miscellaneous terms

to_do/: svn:ignore OpenOffice lock files

inputs/import.stats.xls: Updated with stats from latest import. The import time for SpeciesLink (the slowest datasource) went back down to 9 hours after replacing the slower _merge with _alt.

Added new autogen mappings/VegCore.self.specimens.csv (not currently used)

Merged DwC (including DwC1) and VegCSV mappings into new Veg+ schema. This involves replacing occurrences of DwC and VegCSV with Veg+ (or sometimes VegCore) everywhere, as described in <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV-DwC_merging&gt;.
