plug-ins: port palette-offset to new API.
This first version will just offset by 1 in interactive mode, by default. The GIMP 2 version used to have a GUI, but it was not created by the plug-in itself. I am guessing that maybe our Python wrapper used to create GUI by default. If so, this will have to change. Python plug-ins will be responsible of their own GUI, just like C plug-ins.
