1st new ship is small, has the highest speed, loose handling, and a rapid dodge-roll recharge.

2nd new ship is medium, has medium speed, has the tightest handling, and a laser instead of a dodge-roll, with medium recharge. The laser can destroy small asteroids and slow down medium asteroids.

3rd new ship is large, has slow speed, has poor handling, but has a rapid recharge shield and medium dodge-roll recharge.

This update also included some code refactoring and the start of a dialog system, but these are just underlying bits that are going to come in handy for the next few planned updates.
