    Merge branch 'maint-stock-assistant' into maint #1328
    
    - add support for warnings in stock transaction assistant
    
    - warn if new transaction date is earlier than latest stock account
    transaction date
    
    - reorder pages - input date prior to input stock activity type,
    because the latter depends on the former.

commit fccd07424d56c39a9f61e8965fff5343fc1cd2f1

    [assistant-stock-transaction] reorder of Pages - date before type.
    
    Because the date may be in the past, and the stock balance at that
    date will dictate the available stock txn types available for
    creation.
    
    The available stock txn types is thus dependent on the desired date,
    and must only be initialized when preparing the txn_type page.
