Add ordering traits to VirtualKeyCode (#713)

Browse Source 
Motivation:
This allows VirtualKeyCode variants to be stored in a BTreeSet.
Unlike HashSets, BTreeSets implement Ord and Hash, allowing them to be
keys in a {Hash|BTree}Maps. This is nice, e.g. when implementing
keyboard shortcuts functionality, which maps a set of pressed keys to
some action.
