inputs/UNCC/: switched to new-style import, using the steps at http://wiki.vegpath.org/Adding_new-style_import_to_a_datasource

inputs/UNCC/Specimen/: translated multi-column filters to postprocessing derived columns, using the steps at http://wiki.vegpath.org/Adding_new-style_import_to_a_datasource#Translating-filters-to-postprocessing-derived-columns. reproductiveCondition: use the suggested values at DwC.vegpath.org?reproductiveCondition instead of just joining together the values in flower and fruit.

inputs/UNCC/Specimen/map.csv: usdaRank, infrarank: documented that they should actually be mapped to infraspecificRank*. it is better to map them to taxonRank for now because infraspecificRank is now mapped to VegBIEN.

mappings/VegCore.htm: regenerated from wiki. added EQUIV (also mapped in mappings/VegCore-VegBIEN.csv).

inputs/UNCC/Specimen/map.csv: infrarank: remapped to EQUIV (of usdaRank). usdaRank, infrarank: documented the VegCore term that each would map to.

inputs/UNCC/Specimen/postprocess.sql: infrarank: remove mismapped values "L." (belong in authors, and are already there)

schemas/util.sql: added ?*>= operator (is populated more often than) from wiki.vegpath.org/Postgres_queries#is-populated-more-often-than

bugfix: web/.htaccess: parse dotpath in query string: make dotpath replacement start with ./ instead of / (which would incorrectly create an absolute URL path). this bug only appears when there is a trailing /, because this causes the matched text to be empty instead of a filesystem path with leading /.

bugfix: web/.htaccess: parse dotpath in query string: redirect so REQUEST_URI is populated from REQUEST_FILENAME: need to use - instead of $0 as the redirect destination so that REQUEST_FILENAME is used instead of the empty REQUEST_URI (i.e. the redirect vars are left untouched)

bugfix: web/.htaccess: parse dotpath in query string: need to add trailing / if dotpath so that dest path is URL path, not filesystem path (when trailing / missing, matched path is filesystem path)
