gitk: Improve behaviour of drop-down lists

The drop-down lists used for things like the criteria for finding commits (containing/touching paths/etc.) use a combobox if we are using the ttk widgets. By default the combobox exports its value as the selection when it is changed, which is unnecessary, and sometimes the combobox wouldn't release the selection, which is annoying. To fix this, we make these comboboxes not export their selection, and also clear their selection whenever they are changed. This makes them more like a simple selection of alternatives, improving the look and feel of gitk. Signed-off-by: Paul Mackerras <paulus@samba.org>
