bq. I'd like to get away from static util methods that take 4 parameters

I've created LANG-964 to track the creation of fluent APIs, since this has to wait until 4.0.

> The old implementation (prior to r1532476) of BooleanUtils.xor(boolean...) checked if the provided array contained exactly one boolean with value true. This was changed because it is not the correct behavior for an XOR operation. To preserve the behavior we should add BooleanUtils.isOneTrue(boolean...) and BooleanUtils.isOneTrue(Boolean...) (and possibly the equivalents for isOneFalse).
