+Based on patch from Arch additionally using system's Shaders/

+Resulting paths:
+/usr/share/higan/{Database,Firmware,Shaders,Templates}
+~/higan/ -> ~/.local/share/higan/Systems
+
+Templates+Systems can be changed in ~/.config/higan/paths.bml and
+does not disrupt existing configurations. Shaders will use default
+~/.config/higan/Shaders over system's if it exists.
