Fixed autocommit behavior and error handling

• SqlClosure now works correctly with datasources with enabled auto commit
• Fixed error handling in SqlClosure, now any error (and not only SqlException) leads to rollback as expected

Fixed packaging of 3.0

This is a build-fix release for 3.0, only packaging was fixed. See release notes for 3.0.

API refactoring

This release introduces backward-incompatible API changes!

• New single-point configuration class, meet SansOrm class
• Added optional embedded TransactionManager implementation, can be set up via SansOrm.initializeTxSimple(dataSource);
• Sql-only related things moved from OrmElf to SqlClosureElf
• Dropped deprecated methods

PS: Published artifact is broken, misses com.zaxxer.sansorm.transaction package, use release 3.1 instead.
