Fix artillery micro mining

[mizzao]

Just like missile micro, it should run more the closer the enemy gets, not wait around to get pummeled.

Also, try running it on speed 3 instead of 1.

[mizzao]

Try it with shield 2 instead of regen 2. This will also help on defense with built in regen.

[mizzao]

Also add support for reflection back into artillery...this will help when fighting lasers.
