qutebrowser: Make use of dotter for dir structure

Since we now use dotter we can simplify the dir structure for
qutebrowser a lot. Everything dot-filed earlier can now reside
in simple directories called config (for ~/.config/qutebrowser),
data (for ~/.local/share/qutebrowser), and scripts
(for ~/.local/bin) files.

qutebrowser/data/userscripts/shaarli_add.sh
