writing: Restructure module layout per-program

Similarly to the qutebrowser module we change the layout to have a
program name at the top-level and all required files for that specific
program within, whether they reside within .config, .local or anywhere
else.
We use dotter mappings to achieve this.

+#
+# This tiny script updates all libraries by rebuilding their caches.
+# Useful to invoke after manual edits in one of your library folders
+# if you have many 'sub-libraries' (one library location with sub-
+# directories).
+# You don't have to think about which library you changed stuff in
+# and just get everything updated. Might take a little time but
+# should generally be a quick process ().
