Minecart system overhaul

[tigerw]

Unfortunately we shouldn't be doing the calculations too different from what Vanilla does, because the client runs its own physics simulation and if it doesn't match the server, it will make the minecart seem to jump.

Client seems to be alright with minecarts on that respect. I was able to get them to be stationary on an incline/act generally abnormally without client interference.

So I guess the relevant question here is: What is the development philosophy behind MCServer? Should it be as close as possible to vanilla or should it be better than vanilla?

It should be as close as possible to vanilla gameplay-wise, but better then vanilla performance-wise
