app, libgimp, pdb: passing GimpDrawableFilter across the wire.

Browse source 
A few functions were added, but the main one is
gimp_drawable_get_filters() to request the list of filters applied
non-destructively on a drawable. We can't do much with these for the
time being, but this will come.
WIP.
