Platforms and more!

In this update we included both rising and falling platforms to move around on. Waves of enemies to defeat and added some changing colors to the keys.

For the moving platforms we added start and end locations and let it move smoothly between them back and forth. For the falling platforms we added code that enabled to check if they were "ready" after falling and to reset them. We even added color to the different "stages" so users can see when they were ready, falling, and resetting.

For enemys we added a spawn manager that places them on game start and detects when the number of enemies on the board reaches 0 in order to respawn them. Collision detection enables the player to run into them to deal damage and defeat them. Feel free to grab the new health and mana potions lying around if needed!
