Adds point defense batteries to defend against meteors

- Creates a global meteors list to make it easier to find them.
- Adds point defense mainframe, batteries, projectiles, circuitboards, and R&D designs.
- Adds sound effects and icons for the new machines.
- Original code and sprites ported from Baystation.  Adtapted to our code, added icon states and QoL elements.
