Source code v2.3 version 3 (bugfix)

This is just a small bugfix that does the following:

• Fix tsprintf having compilation errors (can't rewrite arguments from inside a script anymore)
• Make collision buffers 16x more sparse (increase the constant for collision buffer grid size 64-->256) to speed up loading a bit
• Optimize pilloid hitbox script a bit (angle step 30-->60, create inline array instead of using array_create) to speed up gameplay
• Draw "loading" during level transitions so you can tell why the screen is blank
