Disposable - Replace magazines in backpack when launcher fits backpacks

[10Dozen]

When merged this pull request will:

• Allow replacement of magazines in backpacks with launchers, if loaded launcher item fits backpacks (has backpack slot id in launcher_loaded >> WeaponSlotsInfo >> allowedSlots array, implements Allow Disposable Launchers to be replaced in Backpacks #1356)

[commy2]

1. No need to make a config entry for this, because it already is one with the "WeaponsSlotsInfo\allowedSlots" array.
2. No need to maintain a list when we can abuse HashMaps as sets. Lookup in list is O(n) at worts, while lookup in set is O(1).

Disclaimer, suggestions not tested, so there may be typos or logic holes.

commy2 is like: I'll never add this feature!
Also commy2: I rewrite every single line of the feature's PR!

Did you test if it works?

Yeah, works fine.

[commy2]

Should i change other lists/namespaces into hashMaps too?

I don't know. It seems not really necessary.
