CDialog using animated control

CAnimateDlg (located in AnimateDlg.h/cpp) is a simple class derived from
CDialog in order to implement user designed animated control. The user of
the class has to call SetAnimationProperties() method and to pass to it the
ID of the static control that will use as an animation control, number of
frames in the “movie”, array of bitmap IDs in the application resource and
the time-slice between frame (to set the animation speed).
