Weekend Update

This weekend I was able to go through the code and clean up a lot of the AI bugs that I had. Also, I added support to the game so it can be a twin stick shooter and additional debug lines (check the editor in the dev version.)

Here's a brief list of changes-

• Cleaned up code, abstracted objects, and moved things to their own files/namespaces.
• Basic ADSR, need to implement a proper envelope pipeline but the basics are there.
• AI shoot at the player if the player gets too close.
• AI now move a lot better. If the hit the boundary they return to the spawn.
• Player not gets wider the more kills they get. Next step is to implement line.
