Fix a bug in the _collision macro where the mask was not being used. Remove an unnecessary and instruction when drawing heads and body segments.

Lots of general sprite cleanup. Add sprites for the ship and the shots and include collision detection in those routines. I think all of the drawing code is done now, maybe?

Finish the spider sprites and the explosion sprites. Remove "and" masking from the spider and scorpion sprites because they will be drawn first and will not overlap with anything on the foreground. Split the sprite.s file into a series of smaller files for each type of sprite. Add a file to describe the overall plan for the design of the sprites.

Lots of optimization of the sprite code. More scorpions going in the right direction.

Change the way colour works to make it cheaper to overwrite any background colour with green which will make drawing centipede segments faster.

Well, it launches, clears the screen, waits for a key and then quits. But it is a start.
