WORLDEDIT-2476 - Reported by locococo3616

Any time I type //walls, //set or //tool br, etc, and then the block name or ID, it says:
Please report this error: [See console]
java.lang.NoClassDefFoundError: net/minecraft/server/Block

I'm guessing WorldEdit isn't recognizing blocks. Only air works.
Please fix this! I can't really do anything with WorldEdit with this bug in the way.
