    Book-Currency Feature Step 3
    
    Add an option to the File->Properties dialog to select a Currency Accounting Method, and to specify the book-currency and a default gains/loss policy if the 'book-currency' method is selected.
    Revert some changes made in prior commits. Other than storing and retrieving the
    book-currency and policy in book KVPs, the behavior of gnucash has not been
    affected by these changes. The changes made are:
    
         engine/policy.c & .h - define valid policies and their descriptions
             and hints; define functions gnc_get_valid_policy_list and
             gnc_valid_policy
         engine/engine.i - include policy.h; define 'CURRENCY-ACCOUNTING',
             'BOOK-CURRENCY', and 'DEFAULT-GAINS-POLICY' as option names
         engine/test/utest-Split.cpp - revert prior commit that modified test
             function for trading accounts
         engine/test/utest-Transaction.c - revert prior commit that modified test
             function for trading accounts
         libqof/qof/qofbookslots.h - revert prior commit that defined Currency
             Accounting Method; modify definitions of Currency Accounting and Book
             Currency; add definition of default gains policy; keep the previous
             Trading Accounts definition
         libqof/qof/qofbook.cpp & .h - reverted function to determine currency
             accounting method; add function to get book-currency, revert
             previously committed changes to function to determine if book uses
             trading accounts; add function to get gains policy; modify gobject
             properties accordingly
         libqof/qof/test/test-qofbook.c - revert prior modification to test
             function for trading accounts; define tests for book-currency and
             default gains policies
         app-utils/options.scm - define make-currency-accounting-option and
             required support functions
         app-utils/options-util.c & .h - make support functions of
             make-currency-accounting-option available in c code
         app-utils/test/test-options-util.c - include tests for using book-currency
         app-utils/gnc-ui-util.c & .h - define gnc_book_use_book_currency,
             gnc_book_get_book_currency and gnc_book_get_default_gains_policy
             functions
         app-utils/test/test-gnc-ui-util.c - set up tests for new gnc-ui-util
             functions
         app-utils/test/test-app-utils.c - include test-gnc-ui-util.c
         app-utils/test/Makefile.am - include test-gnc-ui-util.c
         app-utils/app-utils.scm - define and export book options for Currency
             Accounting, Book-Currency and Default Gains Policy; export required
             currency-accounting-option support functions
         app-utils/business-prefs.scm - replace the Trading Accounts boolean option
             with a currency-accounting-option and rearrange the order of the
             options
         gnome-utils/dialog-options.c - define functions for set-ui-widget,
             set-ui-value, and get-ui-value for 'currency-accounting' option and
