A "schema" key can be used in the database config when you want to access a different schema without having to always use the dot syntax. This also improves efficiency when you only use tables from one schema.

This avoids conflicts with separate sequences used in test suite fixtures, for example.

The persistModel switch in controllers means describe is not always called, so the sequenceMap is not generated. This patch addresses that by checking the associated model for relevant information when the sequenceMap data is not available.
