plug-ins, pdb: remove the softglow plug-in and add a PDB compat procedure 

Not for 2.10 because the GEGL op's result looks different. I have no
clue how softglow is supposed to look at all, but the removed plug-in
did things that can't possibly be done with physical light in a
darkroom, so chances are the GEGL op is more correct.

Gives an image a softglow effect by intensifying the highlights in the
image. This is done by screening a modified version of the drawable
with itself. The modified version is desaturated and then a sigmoidal
transfer function is applied to force the distribution of intensities
into very small and very large only. This desaturated version is then
blurred to give it a fuzzy 'vaseline-on-the-lens' effect. The glow
radius parameter controls the sharpness of the glow effect. The
brightness parameter controls the degree of intensification applied to
image highlights. The sharpness parameter controls how defined or
alternatively, diffuse, the glow effect should be.
