Describe the bug
Projectiles are blocked by all membranes, rather than abiding the membrane's filter.

Expected behavior
Projectiles should be allowed to pass through Adult-permeable membranes at the very least. Also as a suggestion; there should be an 'inverted primal' that only allows nonliving entities (items, armor stands, minecarts, etc.) through ;P

Additional context
For the sake of simplicity and chicken farms, thrown Eggs are adult entities :P

I never considered non-living entities before, so this is working as intended atm. I'm going to considering this as a feature request and it would need to be implemented in a way so that it doesn't interfere with the original behaviour of the memebranes.
