maskededit.py:
Added parameter option stopFieldChangeIfInvalid, which can be used to
relax the validation rules for a control, but make best efforts to stop
navigation out of that field should its current value be invalid. Note:
this does not prevent the value from remaining invalid if focus for the
control is lost, via mousing etc.
numctrl.py, demo / MaskedNumCtrl.py:
In response to user request, added limitOnFieldChange feature, so that
out-of-bounds values can be temporarily added to the control, but should
navigation be attempted out of an invalid field, it will not navigate,
and if focus is lost on a control so limited with an invalid value, it
will change the value to the nearest bound.
combobox.py:
Added handler for EVT_COMBOBOX to address apparently inconsistent behavior
of control when the dropdown control is used to do a selection.
textctrl.py
Added support for ChangeValue() function, similar to that of the base
control, added in wxPython 2.7.1.1.
