Title: add `Show` impl for Tree{Map,Set}, add .reserve_additional, and cleanup

This is a hodge podge of a couple small cleanup commits. It implements `Show` for `TreeMap` and `TreeSet`, adds `.reserve_additional` to `HashMap`, `HashSet`, `PriorityQueue`, and `RingBuf`, and some removal of commented out code.
