Packaging Update

I had been distributing the game as two files, a PCK file and the executable file. I have noticed that Space Reader has been downloaded a few times, so I decided to make it a bit easier. Since the original release of Space Reader, the game engine has gained the ability to embed the PCK file into the executable, so I have released a new version using this ability.

There is no change in the gameplay (but please let me know if you would like to have a feature added!)
