[feature] list.sort()

[RiedleroD]

sorting arrays is one of those things that seems trivial, but if you don't have a builtin way to do it, it's absolute ass. nobody wants to implement a sorting algorithm from scratch, especially not in a relatively minimal, purely interpreted scripting language.

I'd say:

• numbers are obvious
• strings get sorted by character value (e.g. ["-", "5head", "Aardvark", "Axe", "age", "apple"])
  if equal up until one of two strings ends, the shorter one gets sorted first (e.g. ["", "lig", "ligma", "ligma balls"])
  hit me up if you need help implementing an algorithm for this. a simple dual-pass std::sort should work. I'd have to look at what options the dart stdlib gives us.
• lists are handled like strings, except instead of "character value", items get compared to each other.
• maps aren't sorted and thus can't be analyzed the same way. maybe just length? or maybe we just don't let the user sort a list of dictionaries. It doesn't really make sense to do that.
