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.

+# Both standalone script and qutebrowser userscript that opens a rofi menu with
+# all files from the download directory and opens the selected file. It works
+# both as a userscript and a standalone script that is called from outside of
+# qutebrowser.
+#
+# Suggested keybinding (for "show downloads"):
+# spawn --userscript ~/.config/qutebrowser/open_download
+#     sd
+#
+# Requirements:
+#  - rofi (in a recent version), or bemenu
+#  - xdg-open and xdg-mime
+#  - You should configure qutebrowser to download files to a single directory
+#  - It comes in handy if you enable downloads.remove_finished. If you want to
+#    see the recent downloads, just press "sd".
