schemas/vegbien.sql: added 2013-10-18.Brian_Enquist.Canadensys view

schemas/vegbien.sql: sync_analytical_stem_to_view(): added index on speciesBinomialWithMorphospecies for Brian Enquist's Canadensys request

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

exports/2013-10-18.Brian_Enquist.Canadensys.csv.run: documented runtime (35 min, now that bugs have been fixed)

bugfix: bin/with_all: @inputs default value: use `local`, so that the default value is only set for the current function and doesn't leak back out into the caller. this fixes a bug in subset imports where import_all's Source/import call to with_all would add the .* datasources, but these would then stay in for the import_scrub call, causing extra .* datasources to incorrectly be imported.

planning/timeline/timeline.2013.xls: usability testing: added additional subtask to validate the scientists' extracts (i.e. check that the extract fulfills their request)

planning/timeline/timeline.2013.xls: provide scientists with their requested data: added separate subtask for Brian Enquist's Canadensys extract

planning/timeline/timeline.2013.xls: updated for progress and revised schedule

bugfix: schemas/pg_hba.Mac.conf: made same change for Mac as was made for Linux in r11451

bugfix: schemas/pg_hba.conf: don't allow ident authentication for Unix socket connections, because this apparently prevents having normal, password-based connections ("md5"). note that just switching the order of the ident and md5 entries is not useful, because whichever authentication type comes second will be ignored completely. this problem was previously worked around by just not using Unix socket connections at all, and always specifying "localhost" as the host to force a hostname-based connection. this does not affect the postgres superuser, because they have their own ident line in pg_hba.conf.
