Mining Machines: Implementing ex_act()

Implemented ex_act() in both the ore redemption machine and the mining
vendor. Sparks were added as a feedback for any explosion that call
ex_act() on these machines.
To allow for the reconstruction of these devices, I have implemented
machine recepies and circuitboard definitions for these devices. I also added
R&D recipies for the circuitboards.
Offline and Open icons have been added for both objects.

Squashed all of my previous commits and fixed the leftover garbled code
from my original rebase.
