More hkutil refactoring
All database access goes through hatkirby::database now.

verbly::token, verbly::statement::condition, and verbly::part have been converted to use mpark::variant now. verbly::binding has been deleted, and replaced with a mpark::variant typedef in statement.h. This means that the only remaining tagged union class is verbly::generator::part.
