	Make the height of the previews in data editors configurable.
	Fixes bug #337757.

	* app/widgets/gimpdataeditor.[ch]: add member "view" which needs
	to be set by subclasses. Add style property "minimal-height" which
	defaults to 96. Add style_set() implementation which sets
	editor->view's height to the configured value.

	* app/widgets/gimpbrusheditor.[ch]
	* app/widgets/gimpgradienteditor.[ch]
	* app/widgets/gimppaletteeditor.[ch]: use data_editor->view for
	storing the view widget and removed own view members. Remove
	separate #defines for the view's default width and height, it's
	width follows the dialog anyway.

	* themes/Default/gtkrc: document the default value of 96.

	* themes/Small/gtkrc: set it to 64.
