add select circuit gui for machine and circuits itself (#773)

also fixed some issue with basic machine gui introduced in 9d42b299def1c41bbc7a1f01efe445be28f54399
also retrofitted volumetric flask to use the new INetworkUpdatableItem and GT_Packet_UpdateItem, deprecating MessageSetFlaskCapacity in the meanwhile.

To open the gui for machine, shift-left-click the circuit slot
To open the gui for circuit, click any block (need to be sneaking if it's chest, furnace, etc) with the circuit held in hand.
