The pie is a lie, too!

• Added alpha to actors and blocks. Found an interesting "undocumented feature" : When you make a mesh see-through, you can only see things that were previously drawn. Anything drawn after the see-through mesh, will still be blocked as if the mesh was opaque. The way I minimised this effect was to draw all the opaque things first, then draw the non-opaque.
  
• More work was needed on the editor to rotate actors, so that I can have decorative objects on the walls cheaply.
• Added a basic HP and SP status bars. The SP (special power) will drain as you use your powers, and regenerate as you don't. It is to stop players from spamming powers.
