Space Station Invasion

This is my complete submission of the 2D Platformer Project. Its new title is Space Station invasion. New additions/changes from the tutorial:

• New enemy type with special behavior and its own animations
  • Spider like robot that jumps periodically to make itself harder to jump on
• Added new enemy to level 2 and changed that levels music
• Complete New level Level 3 with a coherent layout and the new enemy type used in it and a different song for background music compared to level 1 and 2.
