fix javadoc + some hints on versions for devs

Simplify the createComponents() methods. - Make stored fields non-stored, if they don't have to be stored. This allows us to specify a reader when adding the field, rather than providing a dummy value and put logic in createComponents() to pass the reader to the tokenizer. - Override TokenStream.reset() in the tokenizers so that the createComponents() methods don't need custom sub-classes of TokenStreamComponents in order to reset the tokenizers.
