SBS version 1.1

I've finally decided to give this game the update I sort of wanted to post launch. Here's what this update does:

-boxes throw fragments everywhere when they are destroyed.

-boxes could hide TNT in them, like usual, but now the TNT is shown once you have damaged the box so it's more clear why they explode.

-Space Place has planet Transmogria in the background, and gravity for box fragments is reduced

SECRET -hold N for a fun effect
