Fixed a bug affecting the Sunlight sprite

This bug caused the Sunlight sprite to continue to show even after Real
View was turned off. Now it disappears properly.
A bit of cleanup in spritelib

Just adding spaces and other small changes. Makes no real difference.
Add visualizations for jumping entrances

Jumping (facing left) and Jumping (facing right) now show outlines of
Mario's exact flight path.
Docstring changes

According to the Python style guide, docstrings should have both
triple-quotes on their own lines. I wrote a quick script to do that, and
applied it to reggie.py and spritelib.py .
Add a disclaimer to the help docs

Added a note that the current documentation on the sprite image system
is now wrong.
