input.Makefile: Documentation: import/steps.by_col.sql: $(steps): Fixed bug where stderr needed to be redirected to stdout so that it would be passed to debug2redmine and included in the file

root Makefile: Datasources: import: Don't pause after "To import all inputs at once" message because this prevents running sequential import with & (as `make import &`)

sql.py: create_table(): Only version temp tables, so that e.g. staging tables are not created with a version # if they already exist. This will help make `make install` idempotent.

input.Makefile: Import to VegBIEN: $(import): Only redirect stderr to stdout if outputting to a log file. This allows unlogged imports to redirect the "Inserted # new rows into database" message, which is output to stdout rather than stderr for use by validation and automated testing, to a separate location.

README.TXT: Documented how to remove an archived import. Moved archived imports commands from Data import to new section Maintenance of archived imports. Changed "Empty the DB" to "Remove the last import" for clarity, and made the command apply just to the public schema and not also to the functions schemas (reinstalling those is documented under Schema changes).

root Makefile: $(rmSchemaCmd) for uninstalling schemas: Escape schema name with "" so that schemas/%/uninstall can be used to remove archived imports (as well as aborted restores of them)

root Makefile: schemas/%.backup: Removed explicit check if file exists because now that the target name matches the name of the file created, the file will be rebuilt only if it doesn't exist

schemas: Ignore log files (from restore operations) for svn

main Makefile: Installation: install: Download input data using new inputs/download target

main Makefile: VegBIEN DB: Schemas: schemas/%/install, schemas/py_functions/install: Ignore errors if schema exists, so that install can be idempotent
