KeySet<T extends KeyboardKey> class

A set of KeyboardKeys that can be used as the keys in a Map.

A key set contains the keys that are down simultaneously to represent a shortcut.

This is a thin wrapper around a Set, but changes the equality comparison from an identity comparison to a contents comparison so that non-identical sets with the same keys in them will compare as equal.
