alphabetical string array sorting

[AndrewAday]

chuck string arrays are now sorted alphabetically rather than by pointer address.

while adding found that the internal chuck type system didn't have a way to get the type of the array as "string[]", rather it reported as "@array", which is strange given the type is correct in chuck code, e.g.

[ "a", "b", "c"] @=> string arr;
<<< arr.typeOf().name() >>> // correctly reports "string[]"
<<< Type.of(arr).name() >>> // returns "@array" ?

found a workaround by using cpp dynamic_cast for runtime type checking
