Change behavior of Enum's to_s and to_sym methods (#326)

This changes the behavior of `to_s` and `to_sym` on Enums.

`to_s` returns a humanized version of the demodularized class name, eg:
"Red," "Slate gray," "Spring green"

`to_sym` converts the demodularized class name to a symbol, eg: `:Red`,
`:SlateGray`, `:SPRING_GREEN`

Note that this was deemed a minor breaking change.
