Use emacs standard ^L (page break) to delimit "pages" (sections)

And enable `page-break-lines' to display each ^L as a line like this:
________________________________________________________________________

And use pageup/down keys to jump between pages, instead of the onerous
defaults `C-x [' and `C-x ]'.
Cleanup: Move `(require 'outline-magic)' to where `outline-magic' is used
Disable fill-column-indicator

because with my current version of Emacs (emacs-24.2.91-94-gbc2fd72) fci
has (or triggers) a bug where the cursor at an empty line is drawn at
column 1 instead of column 0.
Use ipython as the python-mode inferior shell
Remove `my-frame-move': I rarely work with X11 windows now
