A) many things in lombok.eclipse moved to lombok.core to enable reuse with lombok.javac.

B) lombok.javac works now similarly to eclipse's model: We first make big ASTs that are bidirectionally traversable, then we walk through that for annotations.

C) Instead of getting an annotation instance, you now get an object that is more flexible and can e.g. give you class values in an enum as a string instead of a Class object, which may fail if that class isn't on the classpath of lombok.

D) sources to the internal sun classes for javac added to /contrib.
