Re-add debugging statement in regrow
Check :refer before :import if capitalized var is in old :refer

Addresses #27 "Always assumes any capitalized symbol is a class"

Since it is Clojure convention to reserve capitalized symbols for Class
names, we will continue to default to the possible-types order of
[:import :refer].

However, if the old ns-map contains a :refer of the capitalized var, we
switch the search order to [:refer :import] to give it an opportunity of
being found.
