Fixed odd roller bed behavior
Created by: dylanstrategie
- When attached to a roller bed, pixel_y is now manually incremented and removed instead of hardcoded. Might not do much unless the mob is already offset for any reason (in which case it won't reset it)
- Fixed useless if clause that caused mobs to not have their pixel_y reset on roller beds unless they unbuckled themslves
Should address #1302 (closed)
