  - fix catalogdb cvfnc customization

    Hibernate entities were all wrong and needed
    a complete rewrite.
    The scope kept growing and ended up touching a
    lot more of the code than originally planned.
    These changes make the db interactions much easier
    and more straightforward from java.

    The flyway script order had to change to make this
    migration possible.
