[aur-general] Merge request

[Edoardo Maria Elidoro]

Hi, please merge these packages:
https://aur.archlinux.org/packages/clearlooks-bluecurve-gtk-theme/
https://aur.archlinux.org/packages/optimus-gtk-theme/

into these, with a correct name (and with a different category since
GTK2 is basically for Xfce now and not for Gnome):
https://aur.archlinux.org/packages/gtk-theme-clearlooks-bluecurve/
https://aur.archlinux.org/packages/gtk-theme-optimus/

Thanks :)
