New thruster and more systems

The latest update to bling hustle adds 2 more human made systems, Trinidad and Napa.  Trinidad is a system with 3 large planets and their many moons, and Napa is a very small system with lots of friendly turrets and bling.  Like Sool, these are both straight out of Bling Hustle, but have been implemented with the new single-file single-function method.

The options menu now gives players a button to switch between the old pulsed thrusters and the new continuous thrusters.  With continuous thrust mode, the player holds down the mouse, and the ship is continuously pushed and the thruster energy is continuously drained.  Continuous thrust mode seems underpowered at the moment compared to using pulses.  This will get tweaked later.

Shops generated randomly now display their correct name, matching what was and still is shown by the navigation system.
