[PATCH] Makefile: Simplify handling of python scripts

From: Brian Gernhardt <brian@gernhardtsoftware.com>

Message-ID: <1270827245-28958-2-git-send-email-brian@gernhardtsoftware.com>
In-Reply-To: <1270827245-28958-1-git-send-email-brian@gernhardtsoftware.com>

The sed script intended to add a standard opening to python scripts was non-compatible and overly complex. Simplifying it down to a set of one-liners removes the compatibility issues of newlines. Moving the environment alterations from the Makefile to the python scripts makes also makes the scripts easier to run in-place.
