inputs/run: postprocess(): updated runtime (20 min)

mappings/VegCore.htm: regenerated from wiki: rename specimenHolderInstitutions to specimen_duplicate_institutions, as decided in the 2014-03-13 conference call (wiki.vegpath.org/2014-03-13_conference_call#schema-changes-2). note that most schema changes (such as this one) involve mappings changes, which are handled automatically by `inputs/run postprocess; yes|make inputs/{NVS,SALVIAS,TEAM}/test`.

bugfix: inputs/GBIF/table.run: switched to using lib/runscripts/table.run instead of mysql.table.run because some subdirs (Source/) need the regular table.run to work properly. mysql.table.run should instead be used directly by subdirs that use the MySQL install.

inputs/XAL/Specimen/test.xml.ref: updated for sample data.csv, which contains the columns as a CSV. this fixes a bug where a map.csv must be used on a table that contains the same set of columns (ie. not one with no columns if there are any mappings).

fix: inputs/input.Makefile: don't treat *.xml as data files since these are not currently supported

fix: inputs/input.Makefile: removed no longer used special handling of XML inputs, support for which was never added to the Makefile. (bin/map, however, does support importing an XML file into a database.) this fixes a bug in XAL, which used to abort with an error but now just imports an empty table.

fix: inputs/input.Makefile: %/install: don't ignore errors if table does not exist, to ensure a proper errexit. this is now possible because every dir that this target is being run on should be a data dir. (Source/ used to be a metadata-only dir.)

bugfix: inputs/input.Makefile: $(cleanup): need `set -o pipefail`

inputs/VegBank/run: `rm=1 import()`: updated runtime (1 h)

inputs/VegBank/taxon_observation.**/test.xml.ref: updated inserted row count
