remove dummy function prototype

coding style fix

[Cody Garver (codygarver)]

I thought Dan was going to accomplish this using the theme.

review: Needs Information

[Victor Martinez (victored)]

Now that I think more about it, that sounds like a better idea. Specially if Daniel ever wants animations.

I'll modify Granite's expander renderer to use an special style class for the expanders in main categories, and use Granite's renderer from Files, dropping gossip-cell-renderer-expander.* along the way.

Let's leave this as a proof-of-concept.

Only draw source-list expanders when hovering over them.
