Added MaskedTextBox.MatchedText property, which should be used for data binding since it doesn't include any prompt characters like the normal Text property can.
Added the DateTimeEditBox.SetValueToTodayCommand property, that resets to DateTime.Today when executed.
Improved edit boxes to select entire text when a double-click occurs.
Updated the ColorPicker's alpha component edit box to be percentage-based.
修补程序
Fixed a bug in AutoCompleteBox where clicking outside of the control might not always close it.
