Summary
Fixes #16.
This change escapes dialect-specific quote characters inside generated SQL
identifiers. SQLite and PostgreSQL identifiers now double embedded
"characters, and MySQL identifiers now double embedded backticks. Qualified table
names also quote schema components before concatenating them with table names.
The same quoting helpers are used for index DDL names. The regression coverage
checks DML generated from table metadata and DDL generated from index, schema,
and table metadata.
