install.sh assumes .config to exist

[erikvanhamme]

Tested on minimal system.

~/.config does not exist.

Script crashes with:
cp: cannot create regular file '/home/rsq/.config/wayfire.ini': No such file or directory

[erikvanhamme]

Did mkdir ~/.config and started script again.

Completed successfully this time, so a non-braindead user can at least recover from it.

Does http://ix.io/2fxK fix the problem?

Yes, patch works.
