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.
Both bookmarkers can now either send the current page ("s for sending to
shaarli; "w to send to wallabag) or send any link on the current page
(;s for shaarli, ;w for wallabag).
Both have been adapted to the same format, both can be sent a link as an
argument as well (./wallabag_add.sh 'myawesome.blog/entry').
