*	enhance the key_reader program	Kurtis Rader	2016-05-10
	The original `key_reader` program was useful but didn't do much that `xxd` or `od -tx1z` didn't do. Furthermore, it wasn't built and installed by default. This change adds features that make it superior to those programs for decoding interactive key presses and makes it a first-class citizen like the `fish_indent` program that is always available. Fixes #2991
