(VILLAGERS) Path Finding Improvements

It's sad to say that villagers' pathfinding abilities are still as bad as they used to be. Seriously, even Copper Golems seem to have better pathfinding than the villagers themselves. Villagers can detect beds, but they often fail to find a way into a house even when there's a door right next to them. Instead, they just stand outside against the wall, unable to reach the bed inside until zombies attack and kill them. They also struggle to find beds at the second floor. Even if there are stairs leading up to them, they still fail to reach their destination. Hopefully, this problem will be fixed someday.
