Activity entry icons in Journal should not be pre-lighting on rollover (fill/stroke colour reverses)

[garycmartin]

When mousing over activity icons in the Journal, their fill and stroke colours are being reversed as part of a pre-light icon behaviour. This breaks the Sugar ownership colour metaphor for activity entries. Previous Sugar releases has no such pre-light roll over behaviour in the Journal so I'd class this as a regression.

The Journal is currently the only place I can see the rollover icon pre-lite actually happening. Aleksey pointed me to line 1091 where the stroke and fill colours are being reversed for the prelit effect:

 http://git.sugarlabs.org/projects/sugar-toolkit/repos/mainline/blobs/master/src/sugar/graphics/icon.py

        if self._xo_color is not None:
	            stroke_color = self._xo_color.get_stroke_color()
	            fill_color = self._xo_color.get_fill_color()
	            prelit_fill_color = stroke_color
	            prelit_stroke_color = fill_color
	        else:
	            stroke_color = self._stroke_color
	            fill_color = self._fill_color
	            prelit_fill_color = self._prelit_fill_color
	            prelit_stroke_color = self._prelit_stroke_color

Attached is a small patch to fix the issue.
