added it twice, once under <Image>->Layers and additionally under
<Image>->Image->Alpha
Now it is possible to work on a single-layer image without opening the
Layers-dialog for adding an alpha channel.

* app/gimage.c
* app/tools.c
* app/tools.h: Added a field in the Tools struct, preserve.
During gimage_dirty, if this flag is not set the tool will be
reset. This is good for tools that keep a copy of the image
in cache for local manipulation like transform_core.
