Turret Platform

Overview
This new system allows you to place platforms in which you can change turrets at any time.
 * Turrets unlock based on your Workshop Technology Level for your settlements (globally)
 * Placing the platform will automatically pick a random turret that is currently unlocked
 * you can change that by using the Architect Options Menu forcing the system to use the latest placed Turret by default
 * Turrets on platforms do not require external power, so you don't need to screw with wires
 * Turrets on platforms are increased to a minimum of 8 (and a max of 12)
 * All platform turrets give 12 defense, since the unlocks are mainly related to their gameplay effectiveness
 * Defense values of standard turrets: 12 is usually the maximum

NOTE: Set "Default Turret" to "Last Selection" to disable "Random Turrets".
