Thomas Goyne 07da6f6f1b Split json::Number into json::Double and json::Integer
Trying to decide whether an option should be an int or double after
discarding the differences between "1.0" and "1" simply isn't possible,
and even if an option was initialized correctly, if it was changed to a
round number it could get written as an int and break later.

Also convert cajun to tabs because three spaces to indent is terrible.
