profile: cache pixmaps for dive event items

Browse source 
For better scalability, we might replace the dive event icons
by SVGs. Since rendering SVGs is potentially very slow, cache
the pixmaps when the scene is generated.

Note: this does not yet do any SVG rendering, only the caching
of pixmaps.
