* Fixed issues with @FieldDefaults and @Value (you can NOT override

@Value's final-by-default and private-by-default with it; now
appropriate warnings are emitted)
* Builder now errors out on presence of most lombok annotations on an
explicit builder class.
* Builder now takes @FieldDefaults/@Value into account.
* Builder on type now generates the constructor as package private
instead of private to avoid synthetic accessor constructors.
* added a bunch of test cases.
* added a test case feature: If the expected file is omitted entirely
but there are expected messages, the differences in the output itself
are ignored.
* streamlined checking for boolean-ness (removed some duplicate code)
* added 'fluent' and 'chain' to @Builder.
