Install does not work if the source folder has spaces in its name

[Lamecarlate]

I couldn't install the theme, as there were errors on cp and sed lines. This is because I have spaces in the name of many folders. With some little fixes in the install.sh file, it works.

Git diff (let me know if you need more information):
