Add support for change-tracking containers
ODB now supports "smart" ordered containers. Such containers get extra functions for updating and deleting individual elements. Based on this functionality implement two change-tracking containers: odb::vector (equivalent to std::vector) and QOdbList (equivalent to QList). New tests: common/container/change-tracking and qt/common/container/change- tracking.
