... except Audacity.h
This forces us to make each header contain all forward declarations or nested
headers that it requires, rather than depend on context.
Since the move to wxWidgets 3.1.1, NVDA now reads the name of a wxStaticBox. So in this dialog, there is no longer the need for the accessibility name of the NumericTextCtrl to duplicate the name of the wxStaticBox.
Completes James' TimeConverter work
This completes the work that James started. It moves most of the non-GUI
related processing from TimeTextCtrl to James' TimeConverter class.
Other changes include:
1) TimeTextCtrl now expects the format name instead of the format string to be
passed when creating a new instance. I found that almost all cases created the
instance with a blank format string and then set the string after creation.
2) To simplify maintenance and prevent a possible discrepancy between the two,
Increase() and Decrease() were merged into a single routine.
As a result:
1) All cases where a TimeTextCtrl was being used to extract information and
not actually display a control have been changed to use TimeConverter instead.
2) All cases where TimeTextCtrl was being created with an empty format and
then immediately followed by something like this:
tt.SetFormatString(tt.GetBuiltinFormat(c->GetFormat()))
have been changed to pass the format name instead of the format string when
creating the TimeTextCtrl instance.
