- changes to the logic for distributing oxygen through vents: the oxygen generator pushes more oxygen to larger rooms

- bugfixes in HumanoidAnimController.Flip()
- item/itemcomponent statuseffects are stored in a dictionary with the actiontype as a key, so the item doesn't have to iterate over all the components and all their statuseffects
- gap bubble particle tweaking
