[INVALID] wrong blocktype when using /mark

[Wundsalz]

when using /mark to define the 2nd mark of /sp, /c, etc the last placed blocktype is used instead of the selected one.

Minecraft protocol makes it impossible to know what block the player is holding until they click a block. So when you use /mark, I have no way of knowing what block is in your hand. That's something that can only be fixed by a 100% custom client, and some protocol changes. I can't do anything with fCraft alone to fix this.
