[aur-general] Merge request for two GTK Themes

[Edoardo Maria Elidoro]

Hi,
following Maxime suggestions, I renamed two of my packages.
Please merge:
https://aur.archlinux.org/packages/gtk-theme-stepintofreedom/ into
https://aur.archlinux.org/packages/gtk-theme-step-into-freedom/
and
https://aur.archlinux.org/packages/gtk-theme-ubuntusunrise/ into
https://aur.archlinux.org/packages/gtk-theme-ubuntu-sunrise/

Thanks,
have a nice day.
Edoardo
