Local Co-op is now in public_test branch

I have added Local Co-op to the public_test branch:

You can try it out by going to:

There are a couple other updates in that branch as well:

Fighter now starts unlocked, along with a second default captain -- so that a new profile can play co-op immediately. (I always get annoyed at games with local co-op that has to be unlocked first)

20% experience gain overall.

Tuned some flak combos that seemed underpowered.

Drone laser was upped to be more impressive. Starts with burst 4, increased fire rate, and I capped it's speed a bit.

Stingray is a new ship, single turret, sort of like a light warship, more maneuverable but less dakka.
