Implement setting visible ranges on containers.

Browse Source 
- Objects that act as ranged containers now expose a menu option
  which allows the user to input a comma-separated list of ranges to
  show. These need not be contiguous, ergo one can show only
  the first and last elements of an array, or some random set of
  indices in the middle as well.
