**Problem** `VersionManager` is not friendly enough to custom manager, because of: 1. `get_queryset` always return `VersionedQuerySet`, as result it's impossible to override query set class throut `from_queryset` method; 1. `get_queryset` has some extra code which set `querytime` property for query set instance. As a result user should copy this two lines - this is not a pythonic way. **Solution** 1. Move `querytime`-code from `queryset` method into `querytime` decorator. 1. Some `VersionManager` methods use `VersionedQuerySet` methods, so we must ensure that they has deal with `VersionedQuerySet` or it's subclass. If not - we must warned user about potential problems.
