[gimp] plug-ins: clean the new Spyrogimp, rename it and remove old version...

[Jehan <jehanp src gnome org>]

commit e91028df2f9669fe2d98f05a969692695a62003f
Author: Jehan <jehan girinstud io>
Date:   Thu Jan 24 01:05:02 2019 +0100

    plug-ins: clean the new Spyrogimp, rename it and remove old version...
    
    ... from menus.
    The script-fu version is still available through pdb (for scripts) and
    even in the action search. But in menus, only the new Python version
    will be shown. Also update the description and name of the old version
    to make clear it is deprecated in favor of the new plug-in.
    Finally rename the new version to simply "plug-in-spyrogimp" (dropping
    the "-plus" part as we should consider it as a replacement rather than
    as another plug-in, which the "plus" would imply). Anyway the old one
    was called "script-fu-spyrogimp", so there is no name clash.
    
    While at it, do some trailing whitespace cleaning in the new plug-in.
    
    (cherry picked from commit 8729f9a6620d7e8a2c1666446cf0194be6b83709)
