Voting issue, minecarts fixed

I just fixed a voting issue where votes were closed when they got enough support but the form would not really reflect that. Users were still able to change their votes and thus we had some closed votes without the needed support. I hope I was able now to fix this. I re-opened the votes with not enough points.

Minecarts should also be fixed (again). Azkedar kindly looked into the code and made sure that accidental loops of spawning minecarts would not crash the server so easily.

In the meantime I am still doing the backups for the server. There were some technical glitches and I had to start over. I found some better ways to manage the server in the future in the process, so at least some good came out of it.
