Tweaks to initial setup

Increased reinforcements, defences on Oil Rig, reduced skill of enemy ships, reduced amount of enemy ships (removed 2 Shards), added ARAD strike to help soften up naval base, added production for Ifrit and Medusa platforms to player once Oil Rig is captured.

Fixed fail condition, changed AI loadout at mission start to reduce serious platform damage potential.

Moved Shards further away from Oil Rig to prevent them from firing on it.
