Code updated for 5.20+

i am releasing the source i have so far in a little test so people can check it out to see if it is worth pursuing. just copy tyhe code and give it a run. let me know what you really think, or if you have any suggestions.

also, if you know a way that when a user hold the L button down on a window in a "docked" state, if i can get a rectangle (box) to be drawn around the dockwindow and dragged along with the mouse. then, if the mouse reaches a certain distance away from the dockwindow, it automatically undocks.

Looks to work just fine. Two little problems: if you undock to mdi and dock/undock again, titlebar disappears. Also, if you undock to mdi, when you try to move the window, it "jumps" down until you release the mouse. Seems to be a problem with mouse/client coordinates. Maybe handling WM_MOVE?
