fix include style relating to cplusplus libraries ... and adjust INCLUDEPATH accordingly. while i'm at messing with include statements, also re-order the include blocks according to policy and sort them within bigger blocks.

Make canceling of Type Hierarchy evaluation more responsive 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.
