Dev Blog 81 - Late night tutorial improvement, small bug fix

Completely re-worked the tutorial to better convey some information, added a few nifty sprites to help teach the player the basics. Replaced entire soundtrack for tutorial level, and shortened it considerably, simply to teach player basics and jump into level 2.

While doing this work I discovered and fixed a small bug, the tutorial billboard text wasn't being displayed in the right order.

Got some rad new background art pieces, can't wait to implement them tomorrow.

Bed time now though =)
