Mad Meddlers version 13.2.1 released! Phase-through Platforms added! Fixed collision between guard and attack.

Added platforms that the player can phase through. This makes the game much like a platform fighter. 

In some platform fighters, I struggle with getting below the platform fast enough. I hold down and wait a long time to go below the platform, but it fails sometimes. To fix this problem, I make the player instantly fall and phase through the platform if player is crouching.

I added cpu action options to the training mode. It really helps to test and fix the game. I used this testing to fix collision detection with guard and attack. Before, hitting player from behind would fail if the player was guarding. Now, attack from behind is successful.
