- Don't forget to run gimp_ui_init() to get GIMP's styling in plug-ins.
- Process the "key-press-event" signal so that Escape key closes the window (as
it used to before the MR commit).
- Expand vertically the tree view, otherwise resizing the window leaves a lot of
ugly empty space, even though the tree view is still shown incomplete with a
scrollbar.
- Fix the Help button (which was doing nothing).
- Use full words for the "Refresh" and "Help" buttons, rather than icons. Text
is usually prefered for UI discoverability/understandability, unless there is
a space issue (i.e. too many icons for all of them to be words).
- Add a "OK" button too, and reorder the buttons similarly to how we usually
order them.
- Minor coding style fixes (alignments…).
