	* ComboBox.cs: WM_KEYDOWN and WM_KEYUP messages should be sent to the
	textbox if auto complete is used, since we need to navigate over it.
	And in this case don't pass this messages to the base impl. Also hide
	the auto complete list box when displaying the drop down listbox.
	* TextBox.cs: new internal members to expose some of the auto complete
	functionality to combobox.
