quoting facilities set up so that database-specific quoting can be
turned on for individual table, schema, and column identifiers when
used in all queries/creates/drops. Enabled via "quote=True" in
Table or Column, as well as "quote_schema=True" in Table. Thanks to
Aaron Spike for his excellent efforts. [ticket:155]
