[aur-general] cleanup: duplicate packages

[Lukáš Jirkovský]

Hi,
I've found two duplicate packages:
gimp-resynth http://aur.archlinux.org/packages.php?ID=6823
gimp-plugin-resynthesizer http://aur.archlinux.org/packages.php?ID=12273

I think one of them should be deleted. In my opinion it would be
better to remove gimp-resynth, even though it was uploaded first. It's
contributor owns only this package and it doesn't conform so well with
gimp plug-ins naming habit.
