feature request: splicing with transparency

[RetroJ]

Hi,
I would like to be able to -splice with a transparent color when the image I am operating on does not necessarily already have an alpha channel. What are your thoughts on this patch:

We'll get your patch into ImageMagick 6.3.0-3 Beta. Thanks.
