inputs/VegBank/plot_/map.csv: elevation: documented that it has only 5 decimal places of precision, with only 9s and random #s after that

inputs/VegBank/plot_/test.xml.ref: update rowcount

inputs/VegBank/stemlocation_/map.csv: stemcode, stemxposition, stemyposition: remapped to UNUSED. stemhealth is the only data field in this table that is populated, which means that VegBank does not provide data on reobservable stems even though the schema supports it.

inputs/VegBank/observation_/postprocess.sql: added pkey

schemas/VegCore/VegCore.ERD.mwb: regenerated exports and udpated image map

schemas/VegCore/ERD/index.htm: regenerated

schemas/VegCore/VegCore.ERD.mwb: taxon_observation: added observation_in_parent_place, which points to the observation of the same taxon/individual in the parent place. this accounts for VegBank allowing multiple taxonImportances per taxonObservation, which only makes sense when each taxonImportance is from a different stratum and they point to a common taxonObservation for the parent plot.

bugfix: web/.htaccess: auto-detect dotpath in query string: need to include the path ($0) in the replacement, to avoid reverting to the root dir. (mod_rewrite replacements are not like relative URLs, which would interpret ?... as being relative to the current path, not the root.)

bugfix: web/.htaccess: auto-detect dotpath in query string: added missing $ at end of regexp

inputs/VegBIEN/db/.htaccess: allow access to schemas other than the public schema by requiring a schema before the table. currently, this does not break any existing URLs.
