Interactive scripts should use the context palette or gradient rather than the saved one, as the user is more likely wanting to edit the gradient or palette they have actively selected. This is also in line with how 2.10 operated. This patch clears out the palette or gradient property of Python scripts when the GUI is created, so that it uses the context version. It does not affect non-interactive usage.
