Moved retrieval of TableModels into the \FuzeWorks\Database class.

- BREAKING: tableModels can no longer be fetched using the iDatabaseTableModel::__construct() method. From now on users must implement the Database::getTableModel() method using the Factory.
- TableModels now have a few more required methods from the iDatabaseTableModel interface. This change shouldn't impact much
