Made forced loot aware of weapon and armors. Now adds their presets instead.
Made `GetLootThatFitsContainer` aware of items inside container and will fail when container is full
Fixed issue where split stacks were not added correctly to airdrops
Comment improvements
`GetItemsToListOnFleaFromInventory` would not keep the root item at index 0, client requires this
`FindAndReturnChildrenAsItems` now inserts root item at index 0
`CreateMultiOffer` now looks for root item by its id
Updated `CreateSingleOffer` to not choose first inventory item as root, search for it instead
Fixes#318
Moved values out of `ArmorItemCanHoldMods` and into frozen set
Added Tpls to spelling dictionary
Changed list parameters to be `ienumerable` or `icollection` where possible
Made `ArmorItemHasRemovablePlateSlots` use class property directly
Made `ItemHasSlots` return false when checked item doesn't exist instead of throwing an unhandled exception
Folded `HasBuyRestrictions` logic into one line
Added code to validate items fit into airdrop crate
Updated `CreateForcedLoot` and `CreateRandomLoot` to return items with their children
Updated `SetFoundInRaid` to not add a upd to money/currency if it doesn't already have one
