all layers

This I made for people creating sprite animationes. It can reduce the size for all images to 8 bit indexed without mixing up colors that should stay she same, like backgound colors that are supposed to become a transparent color.
It is my first GIMP script anyway and is a modified version of the sg-save-all-layers script.
It just saves a stack of layers as .bmp files with a palette of your choice in the specified directionary.
