- added +1 aircraft capacity for UFO to Hivemind promotion
- changed UFO to bombard attack type with range 1. This allows it to fight properly on water and wreak havoc on cities with its laser cannons, but land units will be a bit harder to hit.
- removed shield graphics and renamed the Photon Shielding promotion to "Unobtanium Armor". I just couldn't get the shield graphics centered properly, so the double effects looked a bit stupid imo.

adjusted size of visual promotion effects on UFO
