Distinguish between Bullet Type and Turret Mode

[johneastman]

Two settings:

• bullet type
• turret mode

This would allow the user to choose a type of bullet and a turret mode separately (for example, the user wanting to shoot an array of bouncer bullets).

Turret modes: single (currently Default), array Bullet types: default, bouncer, splitter

TurretMode component will have two rows, one for the turret mode and another for the bullet type.
