Add windowed support

[matiasba]

Right now it seems that the program searches for the bobber in the center of the primary monitor. It would be very useful to change it so that it takes into account the position and size of the actual wow window. I could run wow in a small window in my second monitor and still be able to do full use of my primary monitor for other things.
