Relex errors: not recognizing "how" as a question-word and ensuing problems

[anitzkin]

-- In "how do you do" relex doesn't interpret "how" at all.

-- In "how are you" relex interprets "how" as a predicate rather than a q-word

-- In predicative "how" questions, such as "How was your dinner?" it works for past tense sentences, but not for present tense ("How is your dinner?"); for present tense sentences it outputs no query-flag nor %copula relation (which it uses for the past tense versions).

[anitzkin]

The first and third points have been resolved. The second one is getting sensible relex output now, but still requires a new r2l rule because it uses how(%copula, $qVar).

The use of _%copula instead of "be" creates a lot of need for redundant rules.
