Updates to MaskedEdit controls from Will Sadkin:

Browse Source 
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.
