head of packaged python-mode needs python-mode installation dir set

[ViktorHaag]

Recent versions of packaged (https://github.com/emacsmirror/python-mode) python-mode seem to require a py-install-directory variable set and provide default-directory as a fallback if the var is not set. We should likely add in something like this before the (require 'python-mode) in starter-kit-python.org to properly set this variable to the installed package version:

(setq py-install-directory
  (car (directory-files package-user-dir t "python-mode-.*")) )

This is probably a relatively fragile gist: it pulls the first item out of the (not reliably sorted) list of file/dirs that match the pattern out of the package directory. It might be useful to have a "get directory for loaded package" function or something to properly get the place that a loaded package ends up at here.

I'm using this setq in my starter-kit-python.el, and it seems to work just fine.

When you set the py-install-directory like this did you get a warning to update your abbrev-file-name? I did under emacs 24.5.
