- Refactored DBIx::Class::Schema::Versioned
- Syntax errors from resultset components are now reported correctly
- sqltargs respected correctly in deploy et al.
+ - Added support for savepoints, and using them automatically in
+ nested transactions if auto_savepoint is set in connect_info.

- Fix t/94versioning.t so it passes with latest SQL::Translator
