-A Flapper esque female outfit
-A Gun Holster Accessory

BONUS: Tommy foam dart gun
This all spawns in either the autodrobe or they can be ordered from cargo for 15 points.
Worth mentioning that I also added an ice pick into the code, as a weapon.
The Tommy gun is now also a toy from the arcade machine.

Special Thanks to Nienhaus for providing the sprites and (attempting) some code for the foam dart tommygun
And Robson for helping me and comitting the fix to the nerf gun.
