I completely revisited QTime, practically everything was touched as
prepared bindings, result sets, serialization, appends, casting.
- added many new QTime related tests
- added a new columns to migrations
- updated seeder
- added a new u_timeFormat data member for models
- updated docs about u_timeFormat
Extracted all the needed using aliases to the base Model class, it helps
to avoid declaring these using-s in the Derived models.
- updated documentation, removed all useless using-s
