Oops.

Forgot to set the learning rate if it's passed as an argument.
Added Image#copy!

This allows duplicating images, and optionally specifying a mask.
Changed VideoCapture#Initialize to support options.

So far you can specify the width, height and frames-per-second of the
capture.
Specc'ed Image#copy!
Make spyglass.rb require the built bundle.
Added an example for the BackgroundSubtractor class.

This shows you on a beautiful, sunny beach background.

Now, where's that margarita again?
