Better Ladders - Carry items & Climb faster  

This tuning mod allows Sims to use ladders while carrying small items (books, dishes, trash bags, laundry, etc.).
It also makes Sims climb roughly 50% faster. This value is a good compromise between speeding up the action and maintaining a realistic animation.
With AlwaysSlideDown version: in addition to climbing faster and carrying items, Sims will now always slide down ladders instead of climbing down. Wheee!

Notes
- Pool ladders and ocean ladders (Island Living) aren't affected.
- Toddlers, cats and dogs still can't be carried while using ladders. This might be added in a future version if I manage to fix the animation for them.
- AlwaysSlideDown: Children and Sims with the childish trait usually get a +1 Happy "Wheeee!" moodlet when sliding down ladders. They won't get this moodlet when they autonomously slide down, only when you explicitly tell them them to slide down (click on a ladder > "Slide Down").
