plug-ins: port the core of foggify plug-in.
There are 2 TODOs to take care of here. First, there is no GUI yet for the interactive mode which will just use the default values. Second, the color argument is not working yet because I had issues passing a GimpRGB as argument (ideally I should create a GimpParamRGB with gimp_param_spec_rgb(), but since we still have the pygobject bugs about manipulating GParamSpec data directly, I can't). Anyway it works with default values, which is already a good first step. :-)
