[PATCH 2/2] Improve look-and-feel of the gitk tool.

[Eygene Ryabinkin <rea-git@codelabs.ru>]

Made the default buttons on the dialog active and focused upon the
dialog appearence.

Bound 'Escape' and 'Return' keys to the dialog dismissal where it
was appropriate: mainly for dialogs with only one button and no
editable fields.

Unified the look of the "About gitk" and "Key bindings" dialogs.
