emitDeclarationSelected does not trigger the tooltip to be shown, it just 
causes the declaration to be use-highlighted, shown in the context-browser, 
and hopefully also in the code-flow view soon.

Showing a tooltip is slightly more complicated right now, see 
ContextBrowserPlugin::showToolTip for example. We should move some of that 
code into a central location, as it already is replicated in a few other 
places.
