Mining Fixes II (#2517)

Seismic Charges are now much cheaper.
KA can now fit into suit storage and the explorer's belt.
Several more items can now fit into the explorer's belt.
KA's with multiple installed modkits can now properly be turned into a RIG module, which keeps said modkits.
RIG thermal drills now work properly.
Mining drones should now spawn with a jetpack.
Mining drone ore bags are now much larger, as they cannot drag crates.
