Preferred divination mode is ignored by main entry point functions

[wombatzus]

The preferred method can be set or customized via the variable i-ching-divination-method

Reading this from the README, I understand it to mean that I can set i-ching-divination-method and it should be automatically used when calling i-ching-query or i-ching-cast or similar functions, if I do not specify a method. Instead, i-ching-divination-method is ignored and i-ching-cast uses i-ching--random-number instead (which never returns changing lines, which is what led me to figuring this out).

Requested: if no optional method param is passed, use method specified by i-ching-divination-method as default.
