Alpha release delays

I wanted to have this out yesterday, but some issues got in the way, the collision system had to be reworked, and the train movement system also needed reworking, I also hit a few bumps in the road with block rendering. These were not things I intended to be fixing.
The good news is that remains to be fixed is the train movement.
I should be able to have it done in the next couple days assuming no other other unexpected problems appear.

Seriously though, sorry for the delays, I'm probably more frustrated at this delay than the rest of you. I've been putting off things I probably shouldn't so I have more time to work on the project.
