Rob Browning's patch with price db & miscellany.

* first iteration of pricedb: we should preserve quotes from old
    binfiles now (rather than throwing it away during the conversion),
    and we can read/write the pricedb as XML.

  * added configure --enable-error-on-warning -- developers, please
    use this.

  * add fancier TAGS handling -- we now track file additions/deletions
    dynamically.

  * add g_hash_table_key_value_pairs: returns a GSList of all the key
    value pairs in a given hash table so you can manipulate them.

    add g_hash_table_kv_pair_free_gfunc: g_slist_foreach helper for
    deleting key value hash pairs when you're finished with the
    results from g_hash_table_key_value_pairs.  You'll still need to
    call g_slist_free as well to delete the spine of the list.

  * continue migration to using backend for all IO and switching from
    top-level Group to top level GNCBook.

  * switch from const gnc_commodity to gnc_commodity in many places,
    after consultation with Bill.
