potential failures with "document"

[aruben-c]

Hi,
First of all: thanks for this great color picker.

I think there are some potential failures if using it in an sandbox or across an iframe.
Because:

"window" is passed to "ColorPicker", but inside, it uses directly "document"
If we look at the code of jquery, it set "document" with:
var document = window.document;
So, "ColorPicker" must also set it from the beginning of the code.
Otherwise, it uses the current "window.document" and not the "document" of the provided "window".

I don't take time to write a test code, I only analyse the code.

Thanks again,
ARuben
