Interactively Add Sides and Segments to Primitives

More hotkeys! The idea is to make possibility to edit parameters like sides, segments and some other, which has most primitives via hotkeys. Similar approach used in Modo. One minute video of demonstration it in modo. How I see the workflow:

1. Add primitive to the scene.
2. Edit parameters via F6 panel directly or use interactive hotkeys (Shift + Mouse Wheel Up / Mouse Drag Up for add sides to cylinder for example)
3. Finish primitive creation by pressing some button? I think a lot better to make possibility to use those hotkeys on any created primitive in object mode until user edited it via edit mode. If user rotate/scale/move object (or did some other nondestructive actions), it still can be edited (of course this should propagate to F6 panel as well).
