I have disabled site-gentoo being loaded automatically on start by
editing site-start. Now I explicitly require it when it's available in
this config, but it can be omitted or toggled in other configs (a
minimal config for example).
We will now put non-config related functions (any elisp libraries or
snippets that I write) into a new ".emacs.d/lisp" directory and separate them from
the config code in the ".emacs.d/config" directory.
During the transition I decided to move and rewrite the logic that
adds all of the libraries to load-path. Now this logic is in two top
level files (load-config.el load-local-lisp.el). I needed to remove
the config-programming-languages module because it conflicted with the
new load-path logic (it was mostly useless anyways).
The man advice functions are deleted in this commit but they will be
added into the new ".emacs.d/lisp" directory soon.
