install.sh - error when using -d

[D3vil0p3r]

When using /install.sh -l --tweaks outline macos -d ./, I get:

GNOME Shell 46.2
Install 2px windows outline version! ...
Macos window button version! ...
Installing './/Gruvbox-Light'...
cp: cannot create regular file './/Gruvbox-Light/gtk-2.0/gtkrc': No such file or directory

and this error interrupts the generation of Gruvbox-Dark. Can you fix the usage of -d argument?

Could you also fix when you use a final / on -d to prevent double //?
