New features:

• Implemented reverse properties
• Implemented object linking on arbitrary properties
• Modified 'dbtype_to_class' to accepts field_name and field_type arguments
• Implemented transactions
• Modified ORM->stat to add ability to load several objects by one query
• Applied cache in ORM::Db::DBI->select_full
• Implemented object cache
• Denied use of intermediate classes without their own tables, because in opposite case when exist 2 intermediate classes derived from one base class then search through one of child classes also finds objects of second class.
• Implemented use of ORM::Expr with 'update'
• Added SQL logging feature to ORM::Db
• Implemented separate layer for DB operations
• Implemented autoreconnect to SQL server after "Mysql server has gone away"
• Added method ORM->stat()
• Added feature to use sealed classes (when primary table does not contain class field)
• Added argument lazy_load to ORM->stat(), which allows to use lazy loaded objects
• Implemented lazy loaded objects, two variants:
  • variant 1: known only 'id' and nothing loaded
  • variant 2: loaded only tables of primary class
• Allowed use of third party classes as object properties
• Calculated meta-properties (ORM::Metaprop incapsulates ORM::Expr)
• ORM should log changes history via ORM::History
• Initial class configuration:
  • global parameter 'history_is_enabled'
  • posibility to enable/disable hostory on per class basis
  • global parameter 'emulate_foreign_keys'
  • method 'new', 'update', 'delete' should accept argument to enable/disable history for particular operation
• Implemented object changes history
• Produce separate initial class from ORM for every separate object model
• Use ORM::Db->qt to quote table names, ORM::Db->qf to quote field names, ORM::Db->qi to quote aliases
• Use ORM::Db->qi to quote table names and field names
• Added redefineable method ORM->dbtype_to_class
