Fix #937

- CE_StatsReport_LoadedAmmo added to language keys (needs translation)
- Stats.xml patched to add CombatExtended.StatPart_LoadedAmmo to Mass stat
- Added file StatPart_LoadedAmmo
- CompAmmoUser now immediately calls UpdateInventory WHENEVER CurMagCount is changed, as it should be
- CompInventory stopped looking at loaded ammo for weight/bulk
- StatPart_LoadedAmmo was added, which does everything previously done in CompInventory, but which is common in current RimWorld versions
- Bulk StatDef now uses StatPart_LoadedAmmo
- AmmoUser CompProperties include a loadedAmmoBulkFactor with default value 0f. This allows RPG-7 and similar weapons to have a higher bulkiness (volume) when loaded.
- StatPart_LoadedAmmo multiplies by loadedAmmoBulkFactor when parentStat is Bulk
