Add multi blocks to FastBreak and GhostHand

[davidsc1337]

Hello there,
I would love to see an option to add multiple blocks to FastBreak and GhostHand features, mainly because I use the client on many Prison servers, and mining two types of blocks is pretty handful.

FastBreak does not even have a block selection.
Multible block support for ghosthand is on the todo list.
