Version 0.86 : Minor tweaks

Just a small patch tonight addressing a few niggling issues.

• Drones no longer fight over the same resource

• Can now control aircraft again

• Units no longer attack units in the same alliance.

• Improved graphics in CEO office.

• Particle Pulse is now a tiny bit more powerful

• Extractor upgrade now deals +1 per extractor rather than +5

• Robot animations now work again over multiplayer.

• Chairman CEO is now harder to defeat.

Cheers Rob
