This pull request brings some of the sprite work which @kugamo
previously did but was not added into master. These sprites allow for
rotational dropships. The mapping has fixed for the escape pods for the
new floors but rotating escape shuttles has not been done.

There is some additional spriting required for the dropships.

# Explain why it's good for the game
Dropships spin me right round.
