Adds a new Arcade Machine.
Made the Orion Trail machine a subclass of arcade. Added designs for its circuit board.
Split up the arcade machines for future expansion. Added Game-Over explanations. A few tweaks and fixes.
Made the parent arcade machine a "randomized" arcade. Mapper can place the parent, and it will auto-magically become one of the existing arcade machines. This code should work for any future arcade machines.
Made emp_act available to all arcades. Made prize vending with filled boxes a proc for use by any arcade machine. Names of your crew are now generated from the same name lists as random characters. Cleaned up the Topic code so there were less duplicate lines.
