Slither

Good news, everyone!

Slither is now taking its first steps towards becoming a full convenience module!

What's fixed?
- Some unused functions have been removed
- There's more consistency
- Problems with setting costumes have been fixed

What's new?

Here's the fun! :wink:
- An `isTouching()` method has been added, to detect collisions
- Several methods for the mouse and keyboard
- `blitText` to simplify text display

While it may not seem like much, mouse and keyboard input (thanks BookOwl!) are MAJOR in making Slither a viable alternative to Scratch!

`isTouching()` will aid heavily in platformers, and `blitText` simplifies PyGame's text command!

The PyPi release will be up shortly.

v0.2.1 had some problems that needed to be fixed.

v0.2.2 fixes them.

Thanks to Omegabyte, sound now works properly in Slither!
Also, with BookOwl's help, there is now a move () steps function in Slither!
I also removed the show and hide functions. You now set if the sprite is showing or hiding with `Sprite.show` (as a boolean).

The help section has also been updated, and many other minor fixes have been added as well!

Any problems? Report an issue and we'll get to it.

Fixed some bugs, updated and moved the examples

Version 0.2 also fixes a major bug with rotations.

Congratulations, everyone! Slither is now released on PyPi!

To sync everything up, I'm also making a release on GitHub, since GitHub allows us to create short blurbs where we can share what's new.
