planning/timeline/timeline.2013.xls: moved non-validation-related tasks after the 10/31 deadline so that these are not taking time away from the validation

planning/timeline/timeline.2013.xls: moved "flatten the datasources to a common schema" under "simplify process of mapping/adding a new datasource" because this is also needed separately for datasources where the left-joining is not part of the validation

planning/timeline/timeline.2013.xls: extended "revisions to VegBIEN schema" to length of "datasource validations (spot-checking)" because schema changes are expected as we add missing fields

planning/timeline/timeline.2013.xls: crossed out and hid completed tasks ("find out amount remaining in BIEN3 budget")

planning/timeline/timeline.2013.xls: datasource validations (spot-checking): extended through the end of November because data providers' fixes on the remaining 10 datasources (wiki.vegpath.org/2013-10-17_conference_call#validation-order) are likely to add significantly to the issues and feature requests associated with these datasources (e.g. the 2nd-round VegBank validation added 4 issues and 5 feature requests). there is also expected to be wait time while data providers are responding (most likely in multiple rounds of feedback).

planning/timeline/timeline.2013.xls: data provider metadata: removed "iPlant can do" because this actually requires Brad/Brian/Bob/other data providers to provide this info. however, this info may be findable on the web for some datasources.

planning/timeline/timeline.2013.xls: moved "data provider metadata" right after "datasource validations" because this is part of the completed database itself rather than the tools to maintain it

planning/timeline/timeline.2013.xls: split "revisions to schema" into "revisions to VegBIEN schema" (part of datasource validations) and "revisions to normalized VegCore" (part of documentation)

bin/import_all: use just import_scrub, not reimport_scrub, because import_scrub now automatically publishes the datasource's import (i.e. removes the temp suffix)

bugfix: inputs/input.Makefile: import: remove the temp suffix once the import is done, so that the full database import doesn't keep the suffix attached to the datasources that import_all didn't import with reimport. removed unused import_publish target (instead use import_temp to invoke just the import without the temp suffix removal).
