Hivebot and Home Update

Soo I love the hivebots but oh dear they're so freaking easy. They are so weak, and die so easily. The radiation and Ion bots feel like the biggest threat.

So added a new purple branch called Precursor.
All have a nice shield, and hopefully pack someform off high offense.
Machine Gun - Should be a stream of bullets. 
Laser - Fires a precursor beam.
Lobber - Lobs a special 'precursor' version of the energy artillery shot.

Also turned the tank class of thinks into blue, similar to ablative/durasteel although a darker color.

Might add loot tables to the precusor ones when I figure that out. And might have spelled precursor wrong somewhere.

And with the new hivebots, just plopped them into the derelict engine.
