schemas/vegbien.sql: locationevent__contributors(): split into set-returning and array-returning functions. sort results by fullname so there is a predictable ordering (VegBank does not include a sort_order in the observationContributor table).

schemas/vegbien.sql: added locationevent__contributors() aggregating function for use in analytical_stem_view

added inputs/VegBank/observationcontributor_/

mappings/VegCore-VegBIEN.csv: mapped event__participant

mappings/VegCore.htm: regenerated from wiki. added EventParticipant table containing event__participant.

bugfix: inputs/VegBank/: taxonOccurrenceID: include the aggregateOrganismObservationID in this so that there is one taxonoccurrence for each stratum's taxonImportance. this allows the different strata to have separate taxonoccurrences that are associated with the stratum-specific locationevents, rather than all being lumped into one taxonoccurrence, with only one locationevent.

schemas/VegCore/ERD/VegCore.ERD.mwb: taxon_observation.observation_in_parent_place: renamed to observation_in_parent_event because the taxon_observation might be connected to a stratum_event which is nested within another sampling_event before it's connected to any sampling_event for a parent plot. this is the case for VegBank data with associated strata.

bugfix: schemas/vegbien.sql: locationevent: locationevent_unique_within_creator unique index on sourceaccessioncode: need to add stratum_id, because the addition of stratum_id to this table instead of a separate stratum_event table (which would have required more schema changes) means we need to use the awkward construction of appending stratum_id to every unique constraint, including ones that ordinarily would just pass through the datasource's pkey

web/links/index.htm: updated to Firefox bookmarks. added Java client- and server-side links. web: split into client- and server-side folders.

planning/timeline/timeline.2013.xls: updated for progress
