Added functionality to cancel the current action in 2d and 3d by pressing the Esc key. The action returns to neutral point (ActionNone).
The GDI object leaking bug couldn't be solved it is still blocking the development. Investigated the WeifenLuo library, the OCC objects drawn using wrappers, the property grid and the tree list view.
Will continue with closing the Iteraton 0.0.10 and schedule the iteration 0.0.11.
