version 0.25

- Path objects can now take a duration parameter. If that is present
   on a Path with set points (ListPath, CirclePath, etc) the traversal
   of the path will skip points or wait at points so that the path
   takes (approximately) duration seconds to complete. On paths with
   no set points (VelocityPath, BrownianPath) the Path will raise
   EndOfPath after duration seconds, on the next call to next()
- Examples now specify a duration for their paths and/or use the
   Paths that accept a duration parameter.
- Game.SpriteGroup takes more care to track all sprites
- Combined penguin.py and Penguin.py in examples/ to prevent collision
   on case insensitive filesystems.
- Added doc/ subdirectory with changelog and start of documentation.
