Removed old redis 2.2 code.
Fixed bug (location of cache_delete_expire_ttl config setting in entity_config).
Removed php 5.4 backwards compat code (since ubuntu now ships php 5.5 packages).
Added new optional $after_cache_func param to cache_lib::single() and cache_lib::multi() to be run the newly cached records have been set.
Applied expire() to entity_record_dao::_delete() instead of just delete();
Added entity_record_limit_dao::_by_fields_offset_multi(), not fully tested yet.
Still missing entity_record_limit_dao::_set_delete_limit_cache_lists_multi() as well as entity_record_limit_dao::by_fields_offset_multi().
