[Enhancement] Command Blocks

==============================================================================
General Help for [Cmdblock]
/cmdblock [block] [cmd] [args] [#ofuses]
[#ofuses]: Any Positive Number, Infinite
Note: If no [block] is specified, then the block in player's hand will be used.
==============================================================================

I was thinking maybe this could be implemented, but i wasn't sure how far you were dzienny.

/cmdblock [block] [cmd] [args] [#ofuses]
[#ofuses]: Any Positive Number, Infinite

When the [#ofuses] is used up any additional clicks on the block will receive the message below:

Sorry, someone has already used this block.
Someone has already used this block. It has 5 more uses left.

Aliases:

/cmdpotion [block] [cmd] [args] [#ofuses]
[#ofuses]: Any Positive Number, Infinite

Sorry, someone has already used this potion. It is now empty.
Someone has already used this potion. It has 5 more uses left.

The additional use of [#ofuses] is so that a certain block may only be used once...twice...or an infinite amount of times, in some cases you would want/need that, and it could be useful. It might be hard to implement that, and I'm not sure if it can be done. Btw, i just thought the potion alias, would make more sense, so that's why i thought that might be better.
