On the beginning of the process of evaluating type hierarchy the evaluating thread may freeze on a first call to Snapshot::updateDependencyTable() for quite a long time (e.g. when showing the type hierarchy for IPlugin class inside Creator project - it may freeze up to about 3 seconds). So, when we want to cancel the evaluation (e.g. when we switch from "Type Hierarchy" into another view or when closing Creator) we may freeze for this period. In order to fix it we pass a future interface as an additional argument for Snapshot::updateDependencyTable() and cancel the update when cancellation of task was requested.
