Modules remain selected even if a turret can’t use it

[Greenfoot5]

Describe the bug

When selecting a turret, modules will be greyed out and you can’t apply them, but they can still be selected if they’re the first turret

Reproduction Steps

1. Have a turret placed
2. Purchase a module that cannot be applied to that turret (it must be the oldest module in your inventory)
3. Select the turret it cannot be placed on, the module is selected but cannot be applied

Expected behaviour

The module shouldn't be selected

With #132 and the overhaul of the inventories, this is no longer the case.
