Slipstream Chests

[Degraine]

I wanted to write a new version of Belt Storages, since the last version available was way too complicated for me to go through and figure out how to update. I've got a prototype that finally seems to be working, bug-free. But I'd like someone (or someones!) other than me to test it out before I officially release it.

No special graphics yet, so everything uses the steel chest graphic for the time being...one thing at a time.
