First go at refactoring arg setting and result handling
Cleans up Select builder
New Select returns bean list
Cleans up return handling
Clean up command creation
Cleans up Insert usage in test
Gives better name to arg
Now tests bean vs variadic explicitly
Throws exceptions for misconfigured Commands
Makes Listen/Notify work with new session
Continues work on exception handling

Exception mappers will be in the future!
Further embraces builder pattern
Reimplements select styles fluently
puts v1 in package names

Correclty uses qote_ident() to correctly quote the
identifier in listen.
Implements delete in new style
Implements update using delete
Adds CopyIn/CopyOut to new way
Adds rollback testing
Makes first stored proc work in new way
Adds more tests to new stored proc handler
